Orthogonal Design and Characteristic Analysis of Turbo Expander

Taking a turbo expander as the research object, the research on the design parameters affecting its performance is carried out. With output power and rotating torque as performance objectives, 16 schemes are designed by orthogonal test method. Based on Fluent, the influence of design parameters such as rotational speed on the output performance and internal flow field of turbine expander is studied, and the simulation results are analyzed by SPSS (Statistical Product and Service Solutions). The results show that: pressure 0.8 MPa, temperature 270 K, rotational speed 3000 r/min, maximum output power about 8.76 kW; pressure 0.8 MPa, temperature 300 K, speed 1500 r/min, maximum rotating torque about 40.63 N·m; in order to achieve the optimum performance target at the same time, based on multi-objective optimization design, the optimum combination is selected in a reasonable range, and pressure 0.8 MPa, speed 2250 r/min, temperature 285 K are selected as the optimum combination, and the experimental verification is completed through the turbo expander test platform.
