摘　　要：对于新落成或改造的发动机室内试车台,为了验证设计结果与相关标准及使用要求的符合性,确认试车间内流场测点布置位置的合理性,需采用CFD手段来模拟试车台内部流场。本文根据某型号大涵道比发动机试车台展开流场分析,解析了CFD仿真过程和细节处理方法,验证了试车台试验能力。For the newly designed or modified indoor engine test stand,CFD method is required to simulate the flow field inside the test stand in order to verify the conformity of the design results,relevant standards and service requirements,and to confirm the rationality of the position of flow field measuring points in the test shop.In this paper,flow field analysis is carried out on the high bypass ratio engine test stand,and detailed CFD simulation process is analyzed,which provides verification means for the test stand construction.
