| 摘 要： | 进、排气系统对涡轮级的性能影响鲜有研究,本文针对增压器涡轮,采用数值方法对全流道大膨胀比跨声速涡轮与进、排气壳进行耦合计算,探索进、排气壳耦合对涡轮级的性能参数影响,结果显示进气壳主要影响静叶10%叶高与50%叶高前缘来流气流角周向分布,静叶排会减弱进气壳带来的参数周向不均匀性,排气壳主要影响动叶尾缘0°与180°周向位置总压与静压分布,进、排气壳耦合涡轮级总静效率比均匀边界涡轮级下降0.25%。

| Abstract: | There is little research on the influence of intake and exhaust systems on turbine performance. In this paper, the numerical method is used to calculate the full-flow large expansion ratio transonic turbine coupling the inlet and exhaust casings for the turbocharger turbine. And it explores the performance parameters of the turbine stage with inlet and exhaust casings. The results show that the inlet casing mainly affecting airflow angle circumferential distribution on the 10% leaf height and 50% leaf height front of the stator. And the stator rows will weaken the circumferential non-uniformity of the parameters brought by the inlte shell. The exhaust shell mainly affects the total pressure and static pressure distribution at the 0° and 180° circumferential positions of the trailing edge section of the bucket. And total to static efficiency of the turbine coupled inlet and exhaust casings is reduced by 0.25% compared to the uniform boundary turbine. |
