Abstract

This paper presents numerical calculations for podded propulsion system using vortex theory and potential panel method. The method discretizes the surface boundary of the body (propeller +pod+strut) and obtained the vortex and propeller surface and potential on strut and pod. A model propeller and strut are considered for these calculations and the results of pressure distribution, flow field around the propeller and hydrodynamic characteristics of the propeller are given. The calculated hydrodynamic characteristics of the propeller are compared with the experimental data and it is shown in good agreement with them.
