摘要/Abstract

摘要： 为研究涡轮喉径、进气间隙等因素对涡轮性能的影响，验证仿真计算和真实试验的差异，提出一套涡轮效率的计算方法，并借助仿真软件对其流场的空气动力学特性进行数值模拟和分析。与实物试验结果进行了比对。研究结果表明：仿真计算与实物试验的结果较为吻合。冲击式涡轮启动瞬态的流场较为复杂，进气角是影响涡轮启动效率的关键因素；减小涡轮间隙、选择与流量匹配的进气喉径均可有效提高涡轮效率。

Abstract: A calculation method of turbine efficiency is proposed in order to study the influence of turbo inlet hose diameter, inlet gap and other factors on the turbine performance , as well as verify the difference between the simulated and test results.The aerodynamic characteristics of the flow field are simulated and analyzed with the help of simulation software. The results show that the simulated results are in agreement with the test results. The start-up transient flow field of impact-type turbine is relatively complex. Inlet angle is a key to affect the start-up efficiency of the turbine. The efficiency of the turbine can be improvedby reducing the gaps of turbine and selecting the throat diameter that matches with the flow.
