摘要
本文通过张量分析,将流体力学中几个基本方程,变换为正交曲线座标系下的通式,以及在圆柱面、球面、椭圆柱面座标系下的表达形式。
In this paper, by means of tensor analysis, several basic equations in fluidmechanics are transfered to general formulas in orthogonal curvilinear coordina-tes and finally we give these expressions forms in cylindrical, spherical andcylindroid coordinates.
