Impact and ricochet of a high-speed rigid projectile from an air-water interface

B Farouk, H Bassindowah, S Segletes

Abstract


A numerical study on a rigid projectile (sphere) ricocheting off a water layer is presented in this paper. The time-dependent three-dimensional simulations are carried out for the impact of a solid metal sphere (with radius r) on a quiescent air-water interface. Three types of metal spheres with specific gravity  values ranging from 7.8 to 2.7 (steel, titanium and duralumin) were considered. The numerical results are compared with analytical solutions and experimental data of the ricochet problem available in the literature. A given range of projectile impact velocity are considered with varying impact angles to determine the critical angle of impact  as a function of the Froude number and specific gravity. A correlation in the form of  is proposed for the ricochet of a solid sphere from an air-water interface.
