摘　　要：本文分析了水垫塘内的淹没射流因受固体边界的约束,其流动特性不同于淹没自由射流,而具有各向异性的特点,论述了应用数值模拟的方法研究该问题的重要意义。应用紊流代数应力模型计算了简单边界条件下淹没碰壁射流的扩散规律及紊动特性,对计算结果与试验实测资料作了比较。It is indicated by the paper that the flow feature of submerged water jet within a water cushion pool is different from the submerged free jet because the jet was limited by the solid boundaries of the pool. It is also demonstrated that numerical simulation is of great importance to the study of the problem. An ASM turbulence model was used to calculate the expansion and turbulence characteristics of the submerged impinging jets, and the calculated results was compared with experimental data.
