CFD Simulations to evaluate the Ship Resistance: Development of a systematicmethod with use of low number of cells.

By Andrea Agrusta, Dario Bruzzone, Cuono Esposito and Igor Zotti

Abstract

The use of viscous CFD simulations to evaluate the resistance of ships is well established. These\ud methods, however, often require a high number of calculation cells with consequent substantial\ud hardware requirements.\ud The objective of this paper is to standardize the operating modes to perform viscous simulations\ud with a rational approach basing on a lower number of cells, for carrying out more rapidly the\ud calculations, without super-computers. This operating mode will be supported by the study of\ud different hulls, displacement and planing, to evaluate a system of localized mesh-sizing of the\ud computational grid that could be standardized for each type of examined hull and to define a\ud protocol to get a good simulation in the shortest time possible
