چکیده
The numerical simulation research of the Underwater Unmanned Vehicle (UUV) shell shape is carried out by applying the modern fluid dynamics numerical simulation technology. In the numerical simulation process, while focusing on the characteristics of the UUV shape, this treatise work properly with its computational model, computational domain, computational grid and boundary conditions. Based on numerical simulation techniques, the UUV shape is multi-objectively optimized by integrated fluid dynamics simulation software-fluent on iSIGHT optimization design platform. Multi-island genetic algorithm is adopted as the optimization algorithm, and Reynolds-averaged Navier-Stokes equation and turbulence model are as well applied in the optimization design process. The results show that by reducing the drag coefficient and the flow noise of the UUV shape, the optimized design has made a significant improvement in its comprehensive performance, which provides a new way for today's optimization design of UUV shape.
