Abstract

The 2D impact phenomenon in calm water, considering asymmetric entry and asymmetric entry withhorizontal velocity is studied. The analysis was performed by using a commercial CFD software (STARCCM+©). The results obtained from the simulations are: pressure distribution, force and roll moment.The study was carried out for typical planing boat sections. Furthermore, the critical conditions requiredfor flow separation from the keel are also determined. The results are compared with models and resultsobtained from some authors and they present very good agreement.
