Description
Technical Field
The invention relates to the field of turbine control, in particular to a bladeless turbine and a fluid working medium control method thereof.
Background
As a power machine structure that uses fluid to impact an impeller to rotate, a turbine has been widely used in the fields of power generation, aviation, navigation, and the like. From the perspective of the application of fluid working media, turbines are generally classified into various types, such as steam turbines, gas turbines, and water turbines. Due to the structural features and operational principles, many technical problems of conventional turbines (e.g., vane turbines) need to be considered in the design, manufacture and application processes, such as the complicated shape of the turbine blades, the tendency of the blades and piston expansion devices to leak air between the stationary housing and the rotary power unit, and the incompatibility of the fluid with high viscosity, high abrasiveness, solid particles, or two-phase flow (e.g., the erosion and contamination of the blades when the turbine working fluid is nanofluid).
The blade-free Tesla turbine driven by fluid shearing force has the characteristics of simple structure, relatively low requirement on manufacturing tolerance, outstanding sealing performance and the like, and during operation, fluid can generate pressure gradient (positively correlated with the square of flow velocity) to be balanced with the centrifugal force of a disc so as to prevent components such as a bearing and the like from being damaged due to over-speed operation. Meanwhile, a centrifugal force field is generated in the operation process, so that the machine body has self-cleaning performance, and the turbine can normally operate under the condition that the working medium is unconventional fuel (such as biomass) and generates solid particles. Therefore, the method has unique adaptability in the aspects of utilizing grinding fluid, fluid containing solid particles and other fluid working media with special physical and chemical properties.
At present, because various circulating systems such as a supercritical steam Rankine cycle and a supercritical carbon dioxide Brayton cycle are in an exploration phase, a Tesla turbine has a remarkable potential for replacing a traditional turbine in production practice due to characteristics of the Tesla turbine. Compared with the conventional vane turbine which is still used at present, the tesla turbine has relatively low energy conversion efficiency, and the main reasons are inlet and nozzle pressure loss, bearing energy loss, end cover surface fluid viscosity loss, fluid dissipation loss in a pressurizing chamber and the like caused by structural characteristics of the tesla turbine. If the problem of energy loss is solved by a targeted research, the application range of the tesla turbine in the industrial field can be greatly expanded by improving the actual energy conversion efficiency of the tesla turbine.
At present, Tesla turbines cannot be put into production practice formally due to relatively low energy conversion efficiency. And for different working mediums of the existing bladeless turbine, when the working mediums are different, the energy conversion efficiency is further reduced.
