Abstract

Viscous flow calculation around a submerged spheroid Z. Virag", G. Trincas^ ^Department of Mechanical Engineering and Naval Architecture, University of Zagreb, Croatia ^Department of Naval Architecture, Ocean and Environmental Engineering, University of Trieste, Italy ABSTRACT On the basis of the standard &-e turbulence model a fully elliptic viscous How calculation around the stern of a six-to-one submerged spheroid is performed. The control-volume method on a staggered grid arrangement is employed using a body-fitted coordinate system. The theoretical predictions on a relatively poor grid show satisfactory agreement with experimental measurements for the flow characteristics upstream and downstream from the stern of the body. In order to improve the result accuracy additional investigations are required as regards the grid dependency and the turbulence modelling. INTRODUCTION In order to predict the total ship resistance the general idea is to solve the pro
