TL;DR: In this article, a multiphase numerical model is developed based on the derived formulation including the discretization formulas of surface tension force, viscous force, interface sharpness force and the treatment of high density ratio near the multi-phase interface, as well as an improved anti-penetration treatment close to the axis.

TL;DR: Wang et al. as discussed by the authors proposed an improved solid boundary treatment technology that combines the dummy particle boundary and the normal flux method to simulate the water entry of a lifeboat in 3D complex geometries.

TL;DR: In this article, a numerical model considering the effect of an internal fluid is established, and the effects of the internal fluid on the whipping response of a fluid filled cylindrical shell subjected to an underwater explosion is investigated.

TL;DR: In this paper, the boundary integral method is used to study the characteristics of bubble jet near a solid wall, and three estimate formulas for bubble jet width, height and velocity are obtained, which have good accuracy to predict the bubble jet height, width, and velocity when W ǫ = 50-1000 kg, h ǔ = 50−500m and γ ǒ = 0.65-1.5.

TL;DR: In this paper, a high-speed camera and an acceleration sensor were used to investigate the cavity evolution and impact loads of high speed oblique water entry of high velocity high-energy projectiles.
