三维复杂流场中TTM法的应用

Application of TTM in the 3D Fluid Field

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．

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.
