Abstract
The motion and distribution of the cloud cavitation in a fuel injection pump are calculated. Numerical code consists of a set of equations in which the radial and transverse motion of bubbles are considered. The computational results examine that bubbles are trapped in the vortex and formed the bubble cloud. These results show qualitatively good agreement with experimental ones. Furthermore collapse of cloud cavitation is simulated numerically. The computational results reveal that the emitted impulsive pressure in the center of cloud exceeds a few GPa and becomes a few hundred times larger than the pressure from a single bubble collapse.
