Pesca Pubblicazione scientifica Computation of Wave-Making Resistance on High Speed Catamaran Using FINE/Marine FILONE TECNOLOGICO TEMA produzione e cattura RIASSUNTO AbstractThe viscous flow around a M331-based catamaran is simulated based on a computational fluid dynamics (CFD) commercial software FINE/Marine, which is an integrated CFD software environment for numerical simulation of mono-fluid and multi-fluid flows around kinds of vessels. The wave-making resistance on a catamaran and the corresponding wave patterns are studied and illustrated in the present paper. Firstly, convergence studies with respect to computational domain size, ramp function, grid number, and time step are performed by the wave-making resistance problem of the catamaran. Then, waves generated by a M331-based catamaran and the corresponding wavemaking resistance on the hull with various traveling speed are simulated. Finally, the ratio of ship-length to its displacement is mainly optimized to obtain a high seakeeping performance with low wavemaking resistance and fast advancing speed. It is confirmed that the FINE/Marine has the capability of prediction of wave-making resistance on the catamaran, and it is also considered to be a promising tool to optimize hull form for high seakeeping performance with fast advancing speed.
