Numerical study CFD of “FANCAT” catamaran`s shapes

Abstract

The main objective of this work is to find the optimal shape from hydrodynamic resistance and waves for a catamaran hull. The main issue is to reduce the hydrodynamic resistance and the wave system generated without influencing propulsion performances. Also because this catamaran is designed for inland it is very important to study the waves system in order to protect the rivers environment.
