By applying momentum integral method, the equation of aerated jet diffusing in water cushion was given. By solving it with Runge-Kuta method, the velocity distribution of an aerated jet in water cushion pool was obtained.

• 应用动量积分法 ,导出掺气水舌的一维扩散方程 ,用龙格库塔法求解 ,得到掺气水舌在水垫塘中扩散的流速分布 ,表明增大水舌掺气量会使水舌在水垫塘中的扩散流速衰减加快 ;
