The characteristic,the forming manner and the strengthening principle of microbubblefield and supercavitation were introduced,examples and effects of using this technique in sugar industry of the world were given.

Edge location and detection in supercavitation s digital imagery;

Research progress of supercavitation hydrodynamics;

Experimental investigation of pressure distribution in ventilated supercavity of underwater vehicle model;

Research on the relation of cavitator profile and supercavity drag reduction;

Numerical simulated research on the supercavity anti-drag characteristic of underwater high speed body;

The homogeneous flow field was solved by N-S equations and k-ε turbulence equations and the supercavity was simulated by modified Rayleigh-Plesset equation based on the structured mesh.

Based on the impulse theorem law, the relationship between the supercavity axis deformation which caused by attack angle of cavitator and the distance along cavity axis from cavitator is analyzed.
