WebNov 7, 2012 · Modeling of cavitation flow as a multi-fluid is a complex problem which does not lead to satisfying results especially when the cavitation is modeled as 3D. Therefore in the engineering practice cavitation flow is often modeled as a single-fluid, where the cavitation area is handled as an area with the pressure lower then the vapour pressure. WebThe paper contain analysis and advancing of the understanding level in the modern state of investigations as whole in new enough field of hydrodynamics for the super high sub- and supersonic speeds of the motion in water of prolate near to axisymmetric supercavitating bodies.
