    Abstract
  • In order to meet the hydrodynamic conditions for supercaviating underwater vehicles moving stable, the cavity closing on a vehicle must have a particular configuration to balance the vehicle’s gravity and the moment suffered. In this study, the influence of tail jet intensity on the steady supercavitating flow was analyzed, and a numerical simulation of ventilated cavitation and tail jet flow field of a 2D underwater vehicle model was performed by using calculation fluid dynamics (CFD). Supercavitating flow was analyzed at different tail jet temperature when the attack angle of the vehicle model was zero degree. The law of influence of tail jet temperature on supercavition was achieved, which agree with experimental result.
