摘要
对带有自由表面的湍流淹没射流（射流喷嘴分别为二维平面和圆形两种）进行了数值计算，控制方程采用守恒形式和标准ｋ－ε模式，对自由表面近似作为对称面处理，采用“刚盖”假定，最后将计算结果与试验进行了比较．
This paper presents the numerical simulations for the two dimensional plane and axisymmetric submerged jet with a free surface.The RNS equation and k ε turbulent model are adopted in the mathematical model,and the free surface is approximated to a symmetric plane in which the “rigid lid” condition is used.The calculating results are compared with some experimental data.
