摘要
Abstract
The one-dimensional theory and the gas dynamic function method,which are often used for the geometrical design of ejector,generally fail to provide the ejector structure with the best performance.Therefore,in this work the Computational Fluid Dynamics method was employed to simulate the flow field and the performance of a steam ejector for waste heat recovery.The effects of key parameters,i.e.nozzle throat diameter,mixing chamber inlet diameter,constant area section diameter,nozzle exit po-sition and constant area section length on the entrainment ratio were investigated.Afterwards,based on the L25 (5 6 )orthogonal a-nalysis,the performance of steam ejector was further analyzed by varying multiple structure parameters.The results show that su-perior performance of steam ejector is achieved by orthogonal analysis method.关键词
