Abstract
The process of underwater vertical launching involves complex issues such as adapter constraints, gas-liquid-solid three-phase coupling and lateral flow. It is the basis and prerequisite for the underwater navigation and air navigation of the submarine-launched vehicle. Combined with the typical phenomena of the underwater vertical launch process, based on the Reynolds-averaged numerical simulation method, the VOF multiphase flow model, the SST K-ω turbulence model, the Schnerr-Sauer cavitation model and overset grid, a full-scale three-dimensional numerical model of the underwater vertical launch of the vehicle is established. The flow and load characteristics of the vehicle at the out-of-tube stage are simulated in various environments such as gas pressure and volume above the launch tube, launch speed, launch depth and lateral flow.
