THE 3-D BOUNDARY LAYER ON ROTATING BLADE
-
摘要: 在附壁的非正交曲线坐标系下,见图1。张量形式的流体运动方程见参考文献。 我们假设:(1)流体呈定常运动;(2)忽略彻体力;(3)TSL条件成立。在基本方程中,引入逆变物理分量代替逆变分量,并根据假设进行简化和量级分析。Abstract: The 3-D boundary layer equations with rotation terms are presented in oblique curvilinear coordinates. After treatment of the governing equations, the basic equations are discretized by backwind difference scheme, and the two parts of them are solved by cross iteration.
