| 摘 要： | 经典S2流面方程在应用中,需要根据计算对象是轴流或径流式叶轮,选择求解的主方程,以避免求解中出现不稳定.本文建立了S2流面半反问题的通用方程,能够直接适合多种形式的叶轮.其次,建立S2流面的环量分布方程,使得在设计环量约束条件下,同时满足了库塔条件,而且环量的空间分布更加光滑连续.第三,提出了S2流面生成的方程,达到了S2流面的光滑性及其与流动的一致性.通过在轴流、向心混流两个计算案例的应用,证明了本文方法的可行性.

| Abstract: | In traditional S2 through flow model,governing equation needs to be selected with respect to axial or radial impeller to avoid possible numerical instability.A new unified flow equation is proposed in this paper for semi-inverse problem solving flow equations on S2 stream face for various types of impellers.A governing equation is proposed for circulation distribution on S2 face to satisfy Kutta condition smoothly.Blade wrap angle distribution is governed by partial equation for continuous and smoothness.Tw... |
