The development of analytical theory and experimental methods for understanding the correlation between explosive properties bubble dynamic characteristics in underwater explosions has important engineering application value weapons ships. Based on assumption an instantaneous detonation, we introduced Jones–Wilkins–Lee equation state to describe high-pressure explosion established initial conditions dynamics calculations. Considering high-Mach-number flow high pressure at boundary bubble,...
The dynamic behaviors of underwater explosion bubbles differ for different explosives. explosive characteristic parameters will result in a greater impact on the motion characteristics bubbles. Based bubble dynamics equation established by Prosperetti and Lezzi [“Bubble compressible liquid. Part 1. First-order theory,” J. Fluid Mech. 168, 457âĂŞ-478 (1986); “Bubble 2. Second-order 185, 289âĂŞ-321 (1987)], we proposed an initial condition state (EOS) form applicable calculating With...
The shock wave characteristics within the near-field are one of most challenging aspects understanding an underwater explosion. latest numerical and experimental techniques were utilized to investigate pressure distribution decay features after a disturbance. governing equations in simulation discretized with fifth-order weighted essentially non-oscillatory scheme space third-order Runge–Kutta time, multi-medium interactions defined resolved via modified ghost fluid method. test system...
To calculate the near-field shockwave propagation of underwater explosions for different explosives quickly and accurately, an improved calculation model, based on Kirkwood–Bethe theory, is proposed. Based detonation theory shock jump conditions, model establishes initial equilibrium conditions shockwave-front state explosion bubble interface. By incorporating a second-order Mach-precision dynamics equation, determines physical parameters enthalpy change functions at expanding stage in real...
