Taking the impactjetflow field of individual rocket as research object, this paper calculates the jet flow field near the back of the launching tube by using the numerical simulation method.
It is found that three patterns may occur to the flow in the pool including free impactjet, submerge impactjet and surface flow according to the downstream water level.
根据高坝下游水垫深度的不同，塘内水流呈现自由冲击射流、淹没冲击射流和面流三种流型。

In laboratory experiments, the expansion Angle and impact area of gas-solid two-phase jet, distribution of the central and outer jer flow as well as the influencing factors were measured.
