Abstract
Aiming at the influence of outboard bulge caused by heat transfer outside on total resistance of the underwater vehicle on the total resistance,the shell and drum profile of the underwater vehicle are optimized in this paper.First of all,the design parameters of the hull profile and outboard drum profile of the underwater vehicle are taken as the design variables,the principal scale is taken as the constraint condition,and the objective function is established with the total resistance of underwater direct navigation as the objective function.Then,the parametric modeling is carried out with the initial principal scale,and at the same time,the parameterized grid model of calculation domain is established.Finally,the computational fluid dynamics(CFD)method is used to analyze the velocity field and pressure field distribution of the underwater vehicle in the underwater direct navigation state,and according to the flow field information,the inlet section,outlet section and outboard drum zone profile of the underwater vehicle shell are optimized.The friction resistance of the optimized underwater vehicle increases slightly,but the viscous pressure resistance and total resistance decrease obviously.Through the optimization of the profile in this paper,the influence of the drum outside the shell on the total resistance is reduced,and the results of this paper can provide a reference for the overall design of the underwater vehicle based on the heat transfer outside the shell.关键词
