Martyniuk O. The hydrodynamics of cavitational bubble in the neighbourhood of a workpiece surface wich is exposed to cleaning

Using the method of reflections of bubble simulating hydrodynamic radiants from boundary surfaces, assuming that the fluid is ideal, the flow is potential and neglecting the influence of force of gravity, the new three-dimensional model of dynamic of development of a cavitational bubble is generated considering the influence of adjacent bubbles and boundary surfaces of a different rigidity and curvature. Based on the analytical research the practical guidelines and procedures of calculation of operational modes of cavitational bathes have been composed for cleaning of workpieces of the composite shape permitting to achieve maximum fast fracture of given contamination at minimum fracture of a composite surface of a workpiece and thus to avoid occurrence of parasitic resonances in technological and treated equipment.
