The nonorthogonal curvilinear coordinate transformation equation is used to disperse and compute the control equation of temperature field,producing the body-fitted grids of the physical plane of the trapezium region.

• 运用非正交曲线坐标转换方程对其温度场控制方程进行离散和求解,生成了梯形区域物理平面的贴体网格,同时应用非正交曲线坐标系对任一角度的梯形区域的流场进行模拟计算。
