Abstract
Water entry bodies are one of the predominating sections in fluid dynamics. The study of physics plays a vital role in understanding the forces, moments, and shape of the cavity developed during the entry process. Some of the examples include wedges, cylinders, cones, submarines, torpedo launching, skipping stones, acrobatic diving; biomechanics, the aerospace industry, etc. This review article focuses on studying the parameters involved during multiphase phenomena like the stages of cavity evolution, effects of entry velocity, entry angle, projectile and nose shape on cavity formation, drag reduction techniques, trajectory control, the effect of waves, depth of submergence during the process of water entry, the effects of cavitation number and Froude's number on cavity evolution, design, and operating parameters, and finally the hydrodynamic characteristics of water entry assessed through different numerical methods and algorithms, including ANSYS, OpenFOAM, VOF Multiphase modeling, lattice Boltzmann method, smooth particle hydrodynamics, Arbitrary Lagrangian Eulerian, finite difference, finite volume methods both numerically and experimentally.
