Focusing on the multiphase flow with heat and mass transition and the motion coupling process of underwater vertical salvo

a numerical calculation model of multiphase flow

slender body motion and deformation load of the adapter module was established to study the characteristics of salvo interference. The results showed that the lateral fluid load and the deformation of adapter module influenced the launching trajectory significantly. In the course of launching

the lateral displacement reached 01 times the length of the body and the lateral attitude angle reached 7°. In addition

the flow backward and bubble overflow process of canister outlet after the launch of the first slender body had a significant influence on the bubble shape

load state of the second slender body

as well as the trajectory. In the current case

the difference of lateral attitude angle between the first and second launching bodies is about 01° at the leaving moment

and the difference of angle velocity reaches 75 (°)/s.
