Abstract
Initial stages of cavitation onset in a stream of liquid flowing past a body is considered. A certain pattern of hydrodynamic phenomena related to the onset of cavitational flows is porposed. It is based on the assumption of a comparatively high cavitation number and that a liquid with a relatively low content of gas-vapor bubbles moves within a certain zone.
Results of calculations are compared with experimentally determined dimensions of the cavitation zone. As an example, the flow past a step in a plane channel is considered.
