摘要
本文导出了适合于无叶喷嘴透平级流线迭代计算的损失模型及流动控制方程组,并据此编制了理想和有损失流的流线迭代计算程序.利用该程序对轴流无叶喷嘴分别进行了理想流和有损失流的数值计算,计算结果与实验值吻合良好.
The present paper introduces a set of equations and a reasonable loss model which are suitable for the streamline curvature calculations of the flows in an axial-flow vaneless-nozzle (AFVN) turbine stage.With the equations and loss model,the ideal flow and the flow considering loss in the AFVN are computed respectively.The calculation results are shown to be coincident with the experimental data.
