Introductory analysis of the influence of the parameters in torpedo force-body shaping design

By the method of the Navier-Stokes equations and second-order equation turbulence model, numerical simulation research on torpedo´s flow fields and hydrodynamic characteristics was carried out, and compared with the theoretical results, the accuracy of numerical simulation method was verified. Focused on five force-body shapes with different parameters, the influences of the parameters in torpedo force-body shape design on the torpedo´s flow fields and its hydrodynamic characteristics were analyzed, which has important value for the torpedo design in future.
