CFD modeling of 2D impact with symmetric entry

Roberto Algarín, Antonio Bula, Oscar Tascón

Abstract


The 2D impact phenomenon in calm water, considering symmetric entry with vertical velocity is studied. The analysis was performed by using commercial STAR-CCM+ computational fuid dynamics software. Thee results obtained from the simulations are pressure distribution and force during impact. The study was carried out for typical planning of boat sections. The results are compared with models and data obtained from some authors and they present very good agreement.

Keywords


2D Impact; CFD modeling; symmetric entry; flow separation.
