When analyzing cavitation erosion, it is necessary to grasp the stress state inside a material due to the bubble collapse process. In this study, the behavior of a vapor bubble collapse and the stress distribution inside the material due to the bubbl

It was shown in the past bench-mark simulation of cavitation that a lift of hydrofoil is underestimated in the break-down region in the condition of transient cavitation at high angle of attack in which cavitation has highly unsteady behavior. The au

The thermodynamic suppression effect of cavitation arising in a NACA0015 single hydrofoil is experimentally investigated in water at mainstream temperatures of T∞ = 20 °C to 140 °C in the present study. The cavity length at T∞ = 140 °C is shor

This study performed a fluid/material coupled numerical simulation of the first stage of a non-spherical collapse of a bubble near a wall and investigated the stress state inside the elastic material of the wall according to the change in the stand-o

Methane hydrate (MH) is one well-known promising energy resources, which has been proved to exist widely around the world and in large amount. Though there are several proposals for efficient utilization system of MH, challenges still remains in the

In submerged laser peening, it has been experimentally clarified that the collapse impact of the bubble which occurs after laser ablation is stronger than the impact of laser ablation itself. Moreover, the experimental results showed the arc height i

Cavitation is a phenomenon in which phase change occurs in a liquid by pressure decrease due to flow acceleration. The phase change is caused by mainly evaporation of the liquid but sometimes by liberation of dissolved non-condensable gas in the liqu
