Understanding and exploring the dynamics of underwater explosions (UNDEX) is of paramount importance in defense, marine engineering, and underwater research due to their potential to inflict severe damage on structures, submarines, and marine life. The following study conducts a detailed examination of the shockwave and bubble dynamics of underwater explosion (UNDEX) in case of increasing hydrostatic pressure, explosive mass, and varying boundary conditions such as the presence of seabed and the ocean surface. A numerical method based upon Riemann problem and Godunov’s scheme is utilized in this study of underwater explosions to predict the shockwave, bubble pulsation including pulsation time, pulsation pressure and bubble expansion and contraction. The numerical method was benchmarked against the published experimental results. Over 96% of accuracy was achieved when comparing the numerical results with the experiment. Finally, a detailed study was conducted to understand the explosion phenomenon for varying charge masses and depth in both shallow water as well as in deep-sea near seabed. The utilized numerical technique proved to be a great method to study the underwater explosion for damage prediction, structural integrity, and the severity of the explosion. |
