In this study, a three dimensional (3D) numerical model of six-degrees-of-freedom (6DOF) is applied to simulate the water entries of twin spheres side-by-side at different lateral distances and time intervals. The turbulence structure is described using the shear-stress transport k-ω (SST k-ω) model...
