水环境数值模拟—SIMPLE算法研究与进展

在查阅了众多国内外有关水环境数值模拟文献的基础上,重点考察应用SIMPLE类算法进行数值模拟并同时提出改进的研究。从算法的收敛速度;校正方程;所采用的网格形式三个方面对SIMPLE算法以及在该算法的基础上经改进得到的SIMPLER、SIM-PLEC、SIMPLEX等SIMPLE类算法的研究状况进行了论述。最后,在以上论述的基础上,对SIMPLE类算法的发展趋势进行了分析预测。

Numerical simulation of water environment——The research and progress of SIMPLE Algorithm

On the basis of consulting abundance of domestic and overseas documents about water environmental numerical simulation,this article had investigated especially on those research that used the SIMPLE and SIMPLE like algorithm to carry on the numerical simulation and proposed to improve method at the same time.From three aspects including the speed of convergences,correcting equation and the adopted grid form,the research development of SIMPLE and SIMPLER、SIMPLEC、SIMPLEX and so on,had been discussed.At last,on the basis of the discussion above,the article had analyzed and predicted the development trends of the SIMPLE and SIMPLE like algorithm.
