Description

  The subject matter relates to turbomachinery. More particularly, the subject matter relates to heat transfer in turbomachines.

  Turbomachinery systems are continually being improved to increase efficiency and lower costs. One way to increase the efficiency of a turbomachine system is to increase the operating temperature of the turbomachine system. To increase the temperature, turbomachinery systems are made of materials that can withstand such temperatures when in use.

  In turbomachinery systems, a casing component (casing) usually accommodates a nozzle / vane component (nozzle portion). Working fluid is directed through the turbomachine system and through the nozzle portion to a set of buckets / blades that rotate to drive one or more outputs, such as, for example, a generator. Because the working fluid is in direct contact with the nozzle portion, the heat from the working fluid often raises the temperatures of the components of the nozzle portion and causes them to expand. If the casing and the nozzle portion are not sufficiently separated from each other, the expansion of the nozzle portion due to heating causes the casing to rub, thereby reducing the efficiency of the turbomachine and shortening the life of the turbomachine system components there is a possibility.

The fluid receiving features 209 can include, for example, one or more slots, holes, grooves, or passages that allow the passage of fluid. In some cases, the fluid receiving feature 209 comprises a fluid guiding feature that directs the flow of fluid (eg, heat transfer fluid) away from the opening 207. The openings 207 direct the heat transfer fluid from the inner cavity 211 inside the cylindrical impingement sleeve 203 to the curved outer surface 205 of the impingement sleeve 203 and then to the curved surface of the turbomachine casing 101, It is configured to form a jet area (which may in some cases be directed back to the fluid receiving feature 209 of the cylindrical impingement sleeve 203). The inner cavity 211 penetrates the body of the impingement sleeve 203 substantially completely (along the axial direction A which corresponds to the main axis of the turbomachine to which the casing 101 belongs and the main axis of the flow to the inlet 208 of the inner cavity 211). It can extend, and the junction between the impingement sleeve 203 and the adjacent plug 213 can be terminated (dead end).

  FIG. 3 shows a schematic perspective view of the turbomachine casing 101 and the impingement sleeve 203 further illustrating the flow of fluid in the casing 101 relative to the impingement sleeve 203. As shown, the turbomachine casing 101 can include an axial flow passage 103 located radially outward of the nozzle cavity 105 (radially away from the central axis of the turbomachine). As known in the art, the nozzle cavity 105 includes a space proximate to the turbomachine nozzle to which the heat transfer fluid is directed to reduce the temperature differential between the inner nozzle portion 107 of the turbomachine and the turbomachine casing 101. be able to. In various embodiments, the axial flow path 103 comprises two parts, namely the first part 103A and an axial downstream side of the first part (far from the fluid inlet), the first And a second portion 103B fluidly connected to the portion 103A. The second part 103B is shown partially occupied by the impingement sleeve 203 in this figure. The second portion 103B can have a larger inside diameter than the first portion 103A, which can accommodate the impingement sleeve 203.

Including. In the turbomachine casing 101, the first lip 215 and the second lip 219 are portions of the impingement sleeve 203 extending between the first lip 215 and the second lip 219 and the second lip of the cavity 103. A circumferential space 115 may be defined between the outer surface 205 of the impingement sleeve 203 and the inner surface 117 of the second portion 103B of the cavity 103 so as not to contact the inner surface of the portion 103B (FIG. 4). In various embodiments, the first lip 215 includes a circumferentially extending slot 223 sized to receive the seal (eg, seal ring) 225. The first lip 215 including the seal ring 225 is configured such that the heat transfer fluid 120 (eg, a gas such as air or a cooling liquid such as water) flows axially through the first portion 103A of the axial cavity 103. The second portion 103B of the axial cavity 103 is sealed from the first portion 103A so as to be flowed into the inner cavity of the impingement sleeve 203 from the first portion 103A. As shown, the heat transfer fluid 120 flows through the first portion 103A of the cavity 103 into the impingement sleeve 203 (via the inner cavity 211 (see FIG. 2)) from the impingement sleeve 203. Outflow through the one or more openings 207 (plug 213 terminates the inner cavity 211 and reverses the flow), and through the circumferential space 115 the second portion 103 B of the axial cavity 103 It can flow to a passage (radially extending passage) 230 in fluid communication with the cavity 105.

In these cases, the plug 413 can include a portion that complements the opening of the inner cavity 111 and that fits (eg, press-fit, interference-fit, etc.) or couples with the impingement sleeve 403. The impingement sleeve 403 may not include the second lip 219 (FIG. 3), and thus the plug 413 may be in contrast to contact with or otherwise coupled to the second lip 219 (FIG. 3). Into the inner cavity 111 directly. FIG. 5 shows an enlarged view of the plug 413 fitted to the second end 221. In some cases, the plug 413 may, for example, be an internal opening 415 for removing the plug 413 from the impingement sleeve 403, for example a seal (for example for holding the impingement sleeve 403 and / or the plug 413 in axial direction) And at least one circumferential slot 417 for receiving a sealing member such as a ring or a retaining ring.

  According to various embodiments, referring to FIGS. 1-5, a heat transfer fluid 120 (eg, as shown in FIG. 3) may be used to help reduce the temperature difference between the casing 101 and the nozzle portion 107. The hot gas from another part of the turbomachine or another machine is directed to the axial flow path 103. That is, when the components in the nozzle portion 107 are exposed to a high temperature working fluid such as gas or steam, these components can heat and expand. If the surrounding casing 101 is not heated as quickly as the nozzle portion 107 or as quickly as the nozzle portion 107, one or more components within the nozzle portion 107 may interfere with the casing 101 ( For example, scraping, touching, etc.) can reduce the performance of the machine.

  As shown and described herein, impingement sleeves 203, 403 are provided within the casing 101 to improve heat transfer within the casing 101 and to reduce the temperature difference between the casing 101 and the nozzle portion. Can. In various embodiments, as shown in FIG. 3, heat transfer fluid 120 enters impingement sleeve 203 (or 403 in FIG. 4) and is in a first direction (eg, substantially parallel to axis A) Flow in the axial direction. Because of the fluid's velocity and direction, the heat transfer fluid 120 blocks the impingement sleeve 203 and the inner cavity 211 at its distal end (the second end 221 of the impingement sleeve 203) (or FIG. 3). Can flow through the plug 413). The plug 213 (413) can redirect the flow of heat transfer fluid 120 from a first direction to a second alternative direction. In various embodiments, the second alternative direction differs by about 90 degrees to about 180 degrees from the first direction of fluid flow. That is, in some cases, a flow of heat transfer fluid 120 directs the heat transfer fluid 120 back toward the first end 217 of the impingement sleeve 203 and also radially outward to the opening 207. When it contacts 213, 413 (for example, having a substantially flat contact surface or a substantially oblique, concave or convex surface) it is substantially reversed. Further, the heat transfer fluid 120 can enter the passage 230 through the opening 207, around at least a portion of the outer surface 205 of the impingement sleeve 203. The at least partial reversal of this flow, as well as the subsequent flow passing through the opening 207 into the passage 230, is the amount of heat transferred to the casing 101 via the heat transfer fluid 120 / the heat transferred from the casing 101 Increasing the amount of H helps to reduce the differential thermal effects from the nozzle portion 107.

  The impingement sleeves 203, 403 (FIGS. 1-5) can be formed in several ways, including their components (e.g., plugs 213, 413). In one embodiment, impingement sleeves 203, 403 can be formed by casting, machining, welding, extruding, and the like. However, in one embodiment, additive manufacture is particularly suited to the manufacture of impingement sleeves 203, 403 (FIGS. 1-6). As used herein, additive manufacturing (AM) can include any process that produces an object by sequential lamination of materials, rather than removal of material in the case of conventional processes. Add-on manufacturing can produce complex geometries without using any kind of tools, molds, or fasteners and with little or no waste of material. When machining a part from a solid billet of metal, considerable parts are cut off and discarded, whereas the material used in additive manufacturing is only the material needed to form the part is there. Additional manufacturing processes include, but are not limited to, 3D printing, rapid prototyping (RP), direct digital fabrication (DDM), selective laser melting (SLM), and direct metal laser melting (DMLM) Can.

Each AM process can use different raw materials, for example, in the form of particulate powder, liquid (eg, liquid metal), sheets, etc., and its reservoir can be held in the chamber 910 of the AM printer 906. . In this case, the impingement sleeves 203, 403 (FIGS. 1-5) can be made of metal or similar material. As shown, the applicator 912 can form a thin layer 914 of raw material that extends as a solid canvas that produces each of the sequential slices of the final object. In other cases, the applicator 912 can apply or print the next layer directly on the previous layer as defined by the cord 920, for example when the material is metal. In the illustrated example, a laser or electron beam 916 fuses the particles for each slice as defined by code 920, but this is not necessary if a rapidly curing liquid metal is used . Various portions of AM printer 906 can be moved to correspond to the addition of each new layer, for example, after each layer, build platform 918 can be lowered and / or chamber 910. And / or the applicator 912 can be raised.

  An AM control system 904 is shown implemented as computer program code on a computer 930. In this regard, computer 930 is illustrated as including memory 932, processor 934, input / output (I / O) interface 936, and bus 938.

A bus 938 provides a communication link between each of the components of computer 930, and I / O device 940 is any device 940 that enables the user to interact with the computer (eg, keyboard, pointing device, display , Etc.). Computer 930 is merely representative of the various possible combinations of hardware and software. For example, processor 934 may comprise a single processing unit, or processor 934 may be distributed over one or more processing units in one or more locations, such as, for example, on clients and servers. Similarly, memory 932 and / or storage system 942 may reside at one or more physical locations. Memory 932 and / or storage system 942 may be any combination of various types of non-transitory computer readable storage media including magnetic media, optical media, random access memory (RAM), read only memory (ROM), etc. Can be provided. Computer 930 may comprise any type of computing device such as a network server, desktop computer, laptop, portable device, cell phone, pager, personal digital assistant, and so on.

  The additive manufacturing process begins by storing a code 920 representing the impingement sleeves 203, 403 (FIGS. 1-5) in a non-transitory computer readable storage medium (eg, memory 932, storage system 942, etc.). As mentioned above, code 920 includes a set of computer executable instructions that define the outer electrodes that can be used to physically generate a chip upon execution of the code by system 900. For example, code 920 can include an accurately defined 3D model of the outer electrode, and various well-known computer aided design (CAD) such as AutoCAD®, TurboCAD®, DesignCAD 3D Max, etc. It can be generated from any of the software systems. In this regard, code 920 may take any currently known file format or a later developed file format. For example, Code 920 is the Standard Tessellation Language (STL) generated for the stereolithography CAD program of 3D Systems, or the American Society of Mechanical Engineers (ASME), with any CAD software being optional Can be with an Additive Manufacturing File (AMF), an Extensible Markup Language (XML) based format designed to allow representing the shape and configuration of any three-dimensional object produced in an AM printer . The code 920 can convert between different formats, convert and transmit into a set of data signals, receive as a set of data signals, convert into codes, store, etc., as needed. Code 920 may be an input to system 900 and may come from a component designer, an intellectual property (IP) provider, a design company, an operator or owner of system 900, or other source. .
