The three-dimensional optimized design of a helium compressor

By analyzing the features of the three-dimensional numerical simulation results for the design scheme of a helium compressor, given were the design direction and guiding principle for its three-dimensional optimized modification design. By employing such methods as adjusting the distribution of blade thickness and the curvature of blade trailing edge profile as well as terminal-bend technology etc., a full three-dimensional optimization design was performed of the aerodynamic design version of the prototype helium compressor. A contrast analysis was conducted of the numerical simulation results before and after the three-dimensional optimized design. The efficiency of the compressor after the three-dimensional optimized design has been increased by 2 percent, effectively limiting the further development of secondary flows.
