摘要：

There are increasing demands for more efficient screw compressor design method which could overcome the problems of rotor profile modification and compressor performance test establishment. As a result, non-uniform rational B-spline curves and computational fluid dynamics theory were introduced as a new method of twin-screw compressor rotor profile design. In this paper, unilateral asymmetric combined cycloid with pin gear arc rotor profile was put as the research object to develop a new rotor profile. Non-uniform rational B-spline curves, which are easy to be modified, are applied to the new rotor profile design. The twin-screw compressor flow field simulation models of both the new and the original one are created. The pressure and velocity distribution law of the twin-screw compressor under the operating speed are explored with the FLUENT software. The simulation results provide the basis for further optimisation of the new rotor profile design. © W. S. Maney & Son Ltd 2015.
