Numerical and Experimental Study of a Spherical Projectile Water Entry Problem and Investigation of Mass and Impact Velocity Effect on Pinch-off Time and Depth

Numerical and Experimental Study of a Spherical Projectile Water Entry Problem and Investigation of Mass and Impact Velocity Effect on Pinch-off Time and Depth

The water entry problem of spherical projectile is simulated numerically and experimentally in this study. An explicit dynamic analysis method is employed to model the fluid-structure interaction using a Coupled Eulerian-Lagrangian (CEL) formulation that is available in finite element code Abaqus. T...
