... of the disk endures higher impact loads and the decline of impact loads along the radius is not uniform in pure water. For impact tests in aerated water, not only a reduction of impact loads but also a longer duration of impact loading is observed. INTRODUCTION The water entry problem has been studied...

... boundary treatment for SPH method is proposed to remove reflection of pressure wave against the solid boundaries of computational domain. The water jet generated at the early stage of water entry and the cavity induced by the free surface sealing are reproduced for the case of the vertical water entry...
