Numerical simulation on wave interference of catamaran with fin stabilizer
Generated wave pattern of twin hull ship is important in analyzing wave interference between hulls. As each hull will generate own wave pattern, which might be identical for both hulls, the interference of wave generated can be either amplification or reduction factor for wave making resistance of t...

| description | Generated wave pattern of twin hull ship is important in analyzing wave interference between hulls. As each hull will generate own wave pattern, which might be identical for both hulls, the interference of wave generated can be either amplification or reduction factor for wave making resistance of the twin hull ship. Free Surface Flow is important to be considered in wave making resistance analysis of twin hull including hull with fin stabilizer, especially for ship operates in shallow water condition. Computational analysis using Computational Fluid Dynamics (CFD) simulation is performed using Reynolds Average Navier-Stokes (RANS) to solve free surface effect problem. The method which applied is Volume of Fluid method, considering two phase condition. The objective of simulation is to predict the wave making resistance and flow pattern of catamaran with and without fin stabilizer, considering the relationship between wave interference and fins stabilizer. The analysis is performed in two configurations, bare hulls and hulls attached with fins. For both configurations, the investigation was conducted with range of model speed from 10 to 20 knots using k-epsilon turbulence model in shallow water condition. The results were based on pressure resistance (Rp) and flow pattern around hulls |
