Specific embodiment
The invention will be further described with attached drawing combined with specific embodiments below, elaborates in the following description more
Details to facilitate a thorough understanding of the present invention, still the present invention obviously can be come with a variety of other ways different from this description it is real
It applies, those skilled in the art can make similar popularization according to practical situations without violating the connotation of the present invention, drill
It unravels silk, therefore should not be limited the scope of the invention with the content of this specific embodiment.
It should be noted that Fig. 1 to Fig. 8 only as an example, its not be according to equal proportion condition draw, and
It should not be construed as limiting in this, as the protection scope to actual requirement of the present invention.
Referring initially to Fig. 1, the axial flow compressor 100 of gas turbine includes rotor and stator.Rotor is a high speed rotation
To the sub-assembly of air-flow acting, for the air work for entering axial flow compressor.Rotor includes rotor drum 1 and along axial more
The rotor blade 2 of grade distribution.Rotor blade 2 includes blade 20, tenon 21 and listrium 22, and fixation is set respectively for blade 20 and tenon 21
It sets in the two sides up and down of listrium 22；Wherein, rotor blade 2 is fixed on rotor drum 1 by tenon 21 and can follow rotor
Drum barrel 1 rotates.Corresponding tongue-and-groove is offered to be cooperatively connected on rotor drum 1 with tenon 21.Blade 20 has 201 He of suction surface
Pressure face 202, and there is leading edge 20a and trailing edge 20b along airflow direction.
With reference to Fig. 2, in the circumferential, the listrium 22 with adjacent two rotor blade 2 of level-one is combined and spliced, adjacent
Two rotor blades 2 between formed runner wall surface C.Specifically, listrium 22 includes the suction face positioned at 201 side of suction surface
Points 221 and positioned at 202 side of pressure face pressure face part 222.Rotor drum 1 is fixed in two adjacent rotor blades 2
After upper, the pressure of the listrium 22 of the suction surface part 221 and another rotor blade 2 of the listrium 22 of one of rotor blade 2
Face part 222 is combined and spliced, to form runner wall surface C.Fig. 2 also shows two combined and spliced seams of listrium 22 5.Upstream is come
Stream F is done work when flowing through runner wall surface C by rotor blade 2, then flows to downstream.Upstream incoming flow F when flowing through runner wall surface C,
Boundary-layer can be formed on runner wall surface C.The principle that boundary-layer is formed can refer to the record of pertinent literature, no longer superfluous herein
It states.
Stator is fixed on the casing 100a of 100 outer radius of axial flow compressor, quiet including being distributed along airflow direction multistage
Blades 3.Stator blade 3 inwardly stretches, and surrounds rotor drum 1 by labyrinth gas seals structure 4.Stator blade 3 is along air-flow side
To the downstream for the rotor blade 2 that same level-one is arranged in.Upstream incoming flow F is rectified diffusion when flowing through stator blade 3.
To avoid touching mill, in the axial direction, rotor between high-speed rotating rotor blade 2 and adjacent stator blade 3
There are gap between the listrium 22 of blade 2 and the listrium 31 of stator blade 3, which is called Inter-stage gap.Due to stator blade 3
There are certain static pressure differences for the import/export of the stator leaf row of composition, and under the effect of this static pressure difference, the integral shroud 30 of stator blade 3 is attached
It closely has between integral shroud 30 and rotor drum 1 of the air-flow f from the Inter-stage gap g1 in the downstream of stator blade 3 via stator blade 3
Radial clearance, then from the Inter-stage gap g2 of 3 upstream of stator blade flow into upstream incoming flow F, this flowing be called do grade between leak.
Requirement with axial flow compressor 100 to performance is higher and higher, and grade pressure ratio also becomes higher and higher, leads to stator leaf
Pressure difference between the import/export of row is higher and higher, so that leakage is difficult to be obturaged completely between making grade.As shown in Figure 1, between grade
The air-flow f of leakage is often returned among sprue with the direction for approaching vertical upstream incoming flow F, the close runner with upstream incoming flow F
The air-flow of wall surface C blends.
As shown in fig. 7, the air-flow of the close runner wall surface C of upstream incoming flow F includes air-flow L1 and mainstream in boundary-layer
Close to the air-flow L2 of boundary-layer in area.The flow velocity S of air-flow L1 in boundary-layer is respectively less than the air-flow in main flow area close to boundary-layer
The 99% of the flow velocity Z of L2, and the flow velocity S of the air-flow L1 in runner wall surface C, boundary-layer is smaller.
When the thickness of boundary-layer is larger, the air-flow that is leaked between grade in the air-flow of the close runner wall surface C of upstream incoming flow F
The ratio of air-flow L1 in the boundary-layer that f is blended is with regard to larger, that is to say, that when the thickness of boundary-layer is larger, between grade
The air-flow of the close runner wall surface C for the upstream incoming flow F that the air-flow f of leakage is blended is mainly the air-flow L1 in boundary-layer, by
It is very low in the flow velocity of the air-flow L1 in boundary-layer, therefore the close stream of upstream incoming flow F that the air-flow f leaked between grade is blended
The flow velocity of the air-flow of road wall surface C is with regard to relatively low.
As shown in figure 5, the thickness of boundary-layer is larger in a comparative example, lead to the stream of the air-flow close to runner wall surface C
Fast V2 is lower, and the flow velocity V1 of the air-flow f leaked between grade is also very low.The air-flow f leaked between the air-flow and grade of runner wall surface C
After blending, biggish blending region M1 is formd, results in biggish starting loss.The flow velocity V of air-flow after blending is
The vector sum of flow velocity V2 and flow velocity V1.
To solve the above problems, needing to increase the flow velocity V2 of the air-flow close to runner wall surface C.As shown in figure 3, suction is facial
Divide 221 there is the first groove structure 221a, pressure face part 222 has the second groove structure 222a；It is circumferentially adjacent for energy
Two rotor blades 2 being set on rotor drum 1, the of the suction surface part 221 of the listrium 22 of one of rotor blade 2
One groove structure 221a is combined with the second groove structure 222a of the pressure face part 222 of the listrium 22 of another rotor blade 2
Splicing, to form runner wall surface C between two rotor blades 2 of circumferentially adjacent setting, flow path wall face has circumferentially
Multiple groove 22a of distribution wave-shaped evenly；
Groove 22a along the runner of two adjacent rotor blades 2 direction extend, and the depth of groove 22a along
Runner direction is gradually increased；The terminal that groove 22a extends is located in the side wall surface of listrium 22.The side wall surface be and runner wall surface C
The plane of intersection.As shown in figure 4, point E, F, G, H are respectively positioned in the side wall surface.
Since the depth of groove 22a is gradually increased along extending direction, groove 22a can preferably accommodate attached
Air-flow L1 in surface layer.Thus, groove 22a can make the gas in boundary-layer during following 1 high-speed rotation of rotor drum
It flows L1 and generates stronger vortex, and then strengthen the momentum-exchange between the air-flow L1 in boundary-layer and the air-flow in main flow area,
So that the thickness of the air-flow L1 in boundary-layer reduces.Comparison diagram 7 is to Fig. 8, after the thickness of the air-flow L1 in boundary-layer reduces,
Thickness in main flow area close to the air-flow L2 of boundary-layer increases.Referring again to Fig. 6, after technical solution of the present invention, close to stream
The flow velocity V2 of the air-flow of road wall surface C is significantly greater than in Fig. 5 close to the flow velocity V2 of the air-flow of runner wall surface C, so that corresponding blending
The area of region M2 is smaller, so that aerodynamic loss caused by leaking between reducing grade, improves compressor efficiency and surge margin.
As shown in figure 3, in one embodiment, the starting point that groove 22a extends is apart from leading edge 20a certain distance L.Groove
Chord length of the starting point that 22a extends apart from leading edge 20a20% to 30%, the depth for the starting point that groove 22a extends is zero.Fig. 3 shows
The starting point D of groove 22a extension is gone out.
In another embodiment, the terminal that the depth of groove 22a extends from the starting point that groove 22a extends to groove 22a
The gradual change in the form of conic section.The depth of groove 22a changes in the rate that front half section changes less than the second half section along extending direction
Rate.
In conjunction with Fig. 3 and Fig. 4, multiple groove 22a are circumferentially uniformly distributed in the form of SIN function or cosine function.?
In circumferential direction, position (position of point E, H in such as Fig. 4) that the blade 20 of multiple groove 22a and two rotor blades 2 is separately connected
It is in crest location.
With continued reference to Fig. 4, in the circumferential, all crest location F and original inner flow passage of multiple groove 22a are in same type
On face, all wave trough position G are in the lowermost end of multiple groove 22a.
For the structural strength for guaranteeing listrium 22, the depth of groove 22a is approximately equal to boundary layer thickness, and is less than or equal to
The half of 22 thickness of listrium.In one embodiment, the quantity of multiple groove 22a is 6 to 12.
