DEVICE AND METHOD OF CREATING HYDRODYNAMIC CAVITATION IN FLUIDS

摘要

The invention provides a fluid hydrodynamic cavitation device (Fig. 1) and method. The device (10) comprises a chamber (30) formed by a wall (40) where the wall has a first orifice (50) and an opposing second orifice (55) that are both in fluid communication with said chamber. The first orifice and the second orifice share the same center-line (X) with the second orifice. The method comprises the steps of: introducing a first liquid stream through the first orifice (50) of the device to create a first liquid jet (65); introducing a second liquid stream through the second orifice (55) of the device to create a second liquid jet (70); creating a high shear intensity vortex contact layer (75) when the first liquid jet interacts with and penetrates the second liquid jet; and creating and collapsing cavitation caverns and bubbles in the high shear intensity vortex contact layer.
