Practical application of Computational Fluid Dynamics (CFD) for predicting flow pattern around a ship hull and calculation of total resistance has been a topic of great interest for researchers in ship hydrodynamics. Today, several CFD tools have been developed to analyse and capture the free surface around a ship. The flow problem is rich in complexity and poses many challenges during simulation. Many mesh sizes were tried during modelling with Realizable k-? and shear stress Transport (SST) k-? turbulent models. The free surface wave pattern and the total resistance (shear and pressure resistances) were calculated. The effects of sinkage and trim were also studied using STAR-CCM+ software implementing a Reynolds averaged Nervier stokes (RANS) equation solver with free-surface capabilities. Predicted results were compared against empirical data showing good agreement. The method is found to be stable and is believed to predict the resistance for any ship with or without trim and sinkage.
