摘要: 针对离心式压气机驱动向心透平系统的流道内存在气动损失的问题，本文利用ANSYS-CFX软件对向心透平系统的流道流场进行了数值仿真计算与分析解。通过对仿真结果与实际的压气机叶轮参数对比分析，验证了仿真方法的准确性。叶轮流场气体流动规律分析结果表明高转速叶轮气体跨声速流动时，主要气动损失有因激波产生的损失、二次流损失以及叶顶间隙造成的损失，并且损失随转速增加而增加。
Abstract: Aiming at the problem of aerodynamic loss in the flow passage of centrifugal compressor-driven centripetal turbine system, numerical calculation and analysis of flow field were carried out to obtain the optimum performance of centrifugal compressor-driven centripetal turbine system. The ANSYS-CFX software is used to analyze the compressor blade. The simulation results are obtained and compared with the actual parameters of the compressor impeller. The accuracy of the simulation is verified. The gas flow law of impeller flow field is studied. The results show that the main aerodynamic losses in transonic flow of high-speed impeller gas are caused by shock wave, tip clearance, and the losses increase with the increase of rotational speed, as well as secondary flow losses.
