摘　　要：以一台四级离心压缩机为研究对象,采用便携式三维激光扫描仪和硅胶灌注方式,有效解决了闭式离心叶轮三维扭曲叶片的测量问题。在此基础上,使用Numeca软件的Autoblade Fitting模块对离心压缩机通流部件的离散坐标进行了几何参数化建模,并利用CFD方法对整机进行了流场分析。研究表明:本文所开展的逆向工程及参数化建模方法能够用于压缩机流场分析。A portable 3D laser scanner with silica gel priming method is used to map 3D twist blades of the shrouded impellers in a four-stage centrifugal compressor. The geometric parameterization modeling for discrete ordinates of centrifugal compressor flow passage components is accomplished with the Numeca Autoblade Fitting module. Lastly, CFD simulations are performed to obtain the compressor＇s aerodynamic performance and internal flow field. The conclusion showed that the reverse engineering technique and geometric parameterization method can facilitate the compressor flow field analysis, which lays the foundation for the future design optimization of centrifugal compressors.
