The collision momentum of condensed particles has little relation with the injection nozzleconfiguration under the same primary nozzle equivalent diameter.
在相同的一次喷嘴当量直径条件下，凝相颗粒的碰撞动量与喷嘴结构之间的关系不大。

Energy law of similitude for laser propulsion refers to the law that there is an optimum nozzleconfiguration for the largest value of impulse coupling coefficient at certain incident laser energy.
The results show that the configuration of submerged nozzle can effectively reduce gas velocity near the aft-dome case, and has better heat security environment.
