摘要：In the current paper,a mathematical model is developed for performance prediction of hard-chin boats which can be used in both semi-planing and planing regimes.The proposed model bases on the 2D+T theory and implements pressure distributions over the length of the hull in order to compute the forces.To determine the forces in the semiplaning range,a function is proposed for the non-dimensional length at which the transom effect appears.Three drag components,which are: frictional drag,induced drag,and spray drag,are considered in the computations performed using an iterative method to satisfy two equilibrium equations.The validity of the proposed method is verified by comparing the predicted trim angle and resistance against the available experimental data.Based on this comparison,it is observed that the proposed method reveals satisfying accuracy in both semi-planing and planing regimes.The method is then used to study variation of hydrodynamic and hydrostatic forces as the hull makes a transition from the semi-planing regime to the planing regime.In addition,different components of the resistance are analyzed.
