We are developing Laser Super Cavity for compact X-ray generator based on Inverse Compton Scattering with several tens MeV electron beam. The laser supercavity increases the laser power and makes small laser beam size at the collision point with the electron beam. A FabryPerot cavity as the laser supercavity has been tested at the KEK-ATF (Accelerator Test Facility) and the design for the incre...

Rotational Supercavitating Evaporator (RSCE) has been proposed as a new technology for seawater desalination. However, it lacks systematic researches on the blade shape of RSCE. In this paper, numerical simulations were conducted on the supercavities formed behind two-dimensional (2D) wedge-shaped cavitators of the RSCE. The cavitating flows around the 2D wedge-shaped cavitators with several ce...

Reducing vessel resistance by using ventilated cavities has been a highly researched topic in the marine industry. There is limited literature on supercavities near free surface, which indicates that their dynamic behavior more complex than conventional due to effect of surface. This paper employs numerical simulations study supercavity, taking into account Numerical can predict gas leakage beh...

Using multiphase computational simulations based on the Navier-Stokes equations, we examine the internal gaseous flows of artificially ventilated supercavities. These simulations indicate that air shear layers that develop on the cavity-wall (the air-liquid interface surrounding the cavity) are an important mechanism of air entrainment. This corroborates previous theory developed for toroidal c...
