摘要:
针对复杂区域流场数值求解中的网格生成,利用偏微分法(TTM)得到贴体网格,较好地解决了因入射角度大而产生的伪扩散,提高计算精度,减小数值误差,保证解的稳定性,减少计算机容量和计算时间,特别是使不规则物体边界容易处理.
Abstract:
This paper uses the TTM method to generate a general curvilinear coordinate system with coordinate lines coincident with all boundaries containing numbers of arbitrarily shapes bodies. Numerical solutions for the furnace in a power plant using this coordinate system generation will show excellent comparison with the analytic solution.
