STUDIES ON VELOCITY FIELDS AROUND THE CAVITATION VORTICES GENERATED BY THE MODEL OF A ROTATING BLADE

摘要

The elimination of hazards caused by cavitation phenomena is an important issue to be considered in the design of process equipment including flow machinery. These hazards are: cavitation erosion, efficiency decrease as well as vibration and noise. One of the most intensive and dangerous forms of cavitation is vortex cavitation that accompanies the operation of hydraulic machines in which components comprised of rotating blades are applied.
