ABSTRACT
In the present work, a systematic parametric study is performed to investigate the effect of various environmental and geometrical parameters, such as wave steepness, wavelength, and free surface on bow slamming load using a CFD-based one and a two-way coupled method. In the case of one-way coupling, the ship’s heave and pitch motions are determined using a standard potential theory-based method. Subsequently, the estimated values are given input to a finite volume-based commercial CFD solver to compute slamming pressure. In the case of the two-way coupled method, the ship motion and slamming pressure are captured through the CFD solver. A scaled KRISO container ship (KCS) model is chosen for the analysis. Initially, the present numerical model is compared with state-of-the-art numerical and theoretical results to establish the correctness of the proposed model. A series of cases are then chosen to check the dependency of bow slamming pressure on various physical and geometric parameters using one and two way coupled methods. The results show that both methods give a similar physical understanding of the problem. However, there are distinct differences in the magnitude of the obtained results.
