Abstract

depths relative to the free surface. The datapoints for the regression analysis were obtained using Computational Fluid Dynamics (CFD). The regression analysis used the Curve Fitting Toolbox from MATLAB and employed several methods to obtain the optimal empirical equations to describe the hydrodynamic coefficients with respect to forward speed and submergence depth in the form
