Abstract

A numerical method combined with dynamic overset technique is introduced to predict the strongly nonlinear motion and instantaneous flow field during submarine's emergency surfacing. Simulations of surfacing maneuvering for a buoyantly rising submarine in calm water and waves were carried out based on Reynolds Averaged Navier-Stokes (RANS) equations and Volume of Fluid (VOF) model. Validation for numerical wave-making was performed with satisfactory results before these simulations. Reasonable motion characteristics and flow physics around the submarine demonstrate that the current method is feasible and potential for direct computation of submarine's emergency surfacing in severe environments.
