稳压室环腔结构对压气机进口流场均匀性影响

摘要

Based on the design requirements of gas turbine plenum of output shaft, four plenum models with typical ring cavity structure were built, structured grid and numerical simulation method were applied to calculate on different models from inlet flow field and intake resistance, and then obtained the best ring cavity form of inlet plenum. The results can provide a reference for the actual design.%根据前输出轴燃气轮机稳压室的设计要求，建立了4个具有典型环腔结构的稳压室模型，应用块结构化网格及数值模拟的方法，从进气流场均匀性和进气阻力两个方面对不同模型进行计算分析，得到了最佳的进气稳压室的环腔结构形式。研究结果可为实际设计提供参考。
