摘要
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。并在同一条件下与直角坐标系所模拟的温度场进行比较,说明了非正交曲线坐标方法的正确性和可行性。
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. Simultaneously nonorthogonal culvilinear coordinate system is applied to analog computation of the fluid field of a random angled trapezium region, which is compared with the analog temperature by orthogonal coordinate system under the same conditions. This illuminates the validity and feasibility of nonorthogonal curvilinear coordinate method.
