摘要
本文提出了一种能够考虑压力边界条件的ＳＩＭＰＬＥ－Ｐ（Ｐｒｅｓｓｕｅ）算法．该算法对已知压力未知流量的情况，计算性能大大优于ＳＩＭＰＬＥ算法．文中指出，一个完整的压力边界条件实现必须同时考虑到边界内部控制体的影响．算例表明，本文提出的方法是切实有效的．
A SIMPLE type algorithm,which is called SIMPLE-P,is presented here.The new algorithm lays emphasis on pressure boundary conditions which are ignored by SIMPLE.The SIMPLE-P algorithm has a great advantage over SIMPLE algorithm when the boundary pressure,instead of velocity,is given.It is pointed out that to obtain the full treatment of pressure boundary conditions,the effects ofboundary inner control volume must be taken into account.The examples given here prove that the SIMPLE-P algorithm is quite effective.
