曲线坐标系中叶轮机内粘性气体动力学方程式

Viscous Gasdynamical Equations for Turbine in Non-Othogonal Curvilinear

本文采用矩阵微分算子,推导出了适用于任何曲面或流面的气动力学方程组粘性项和热传导率在曲线坐标系中的表达式及其简化式。建立了半正交曲线坐标系中的流面粘性气动力学方程组。

In this paper expansions and simplified expansions of viscous and heat transfer item for gasdynarnical equations using mattix differential to suit any curve surface or flow surface has been derived in non-othognal corvilinear coordinates. Viscous gasdynarnical equations for flow surface are built too in holf othogonal corvilinear coordinates.
