Analytical modeling and calculation of hydrodynamic pressure field caused by Rankine rotating body based on potential flow theory

Abstract

This paper focus on establishing and solving the theoretical model of the pressure distribution caused by the submarine, which can be simplified to Rankine rotating body, by using the boundary element method, which is based on the spatial potential flow theory. With consideration of the characteristics of the sailing Rankine body in an open water, the submarine hydrodynamic pressure field can be calculated. The theoretical model is to be confirmed by comparing with the experimental results of the hydrodynamic pressure field at different depths, which can better meet the safe navigation of the submarine.
