摘　　要：基于时间推进有限体积法求解周向平均Navier-Stokes通流控制方程,开发涡轮通流计算程序。结合对涡轮内部流动规律的深刻认识,加入B-L端壁紊流模型和涡轮落后角模型,对GE-E3双级高压涡轮和GE-E3五级低压涡轮进行通流性能预测分析,验证了本通流程序的可靠性;并将通流程序应用于某航改地面燃机一体化设计涡轮系统性能预测和分析,对于研究涡轮部件之间性能匹配和气动布局具有工程应用价值。The Time-promoted finite volume method is used to solve the circumferential average Navier-Stokes throughflow control equations, and the turbine throughflow calculation program is developed. By the deep understanding of the internal flow rules of the turbine, the B-L end-wall turbulence model and the turbo backward angle model, this paper analyzes and predicts the throughflow properties of the GE-E3 two-stage high pressure turbine and GE-E3 five-stage low pressure turbine and uses the result of this analysis and prediction to verify the reliability of the throughflow program and then, applies the throughflow program to the performance prediction and analysis of a turbine system for an aero-derivative ground turbine integrally designed. It is of certain engineering application value for studying the performance matching and aerodynamic layout among turbine components.
