摘要
本文对作者早先提出的用熵关联的时均N-S方程组作了新的推导和物理解释,并具体编程序求解了它的二维流函数形式。计算用了任意曲线坐标及K-ε模型。算例是一环形透平静叶栅,算得的沿流向质量平均总压损失与实验数据(VKI)作了比较,证明是可信的。
A new derivation and physical interpretation of the entropy-linked ensemble-averaged Na-vier-Stokes equations, which was put forward by the present author years before, was performed. By introducing stream function, using a non-orthogonal curvilinear co-ordinates system and K-ε EVM, the 2-D form of the new equations has been coded into a computer program. The calculating example is a VKI annualar turbine nozzle guidevane. By comp aring the calculated pitchwise mass-averaged total-pressure loss distribution with the VKI data, it was showed that the calculating results are beleavable.
