Governing equations of a modified k - model is derived in a three - dimensional cylindrical polar coordinate system , and an available equation is produced
首先给出单相螺旋流流场在三维圆柱坐标下的修正-湍流模型的控制方程，得出控制方程组的通用形式。
A discretization equation is derived by using a finite volume method in three - dimensional cylindrical polar coordinate system . algebraic equations are solved by iteration with a line - by - line method that is a combination of tdma in axial and radial directions , ctdma in tangential direction and adi method in three directions . the pressure and velocity coupling are solved with the simple algorithm
在三维圆柱坐标下，利用有限体积法推导离散方程；在轴向与径向用三对角矩阵法( tdma ) ，在周向采用循环三对角矩阵法( ctdma ) ，采用交替方向亚松弛叠代法( adi )求解方程；推导同位网格下的压力修正方程，用simple算法处理速度与压力的耦合；为加速收敛，采用适当的松弛因子。
