Dynamics of a cavitation bubble between oblique plates

Experiments were performed to investigate the collapse dynamics of a cavitating bubble generated between pair symmetrically arranged oblique plates. A 2.0 mm gap was left at converging end two plates, which inclined an angle 10°. focused laser beam cavitation about 4.0 in diameter, four different locations that placed on centerline glass high-speed camera captured bubble's frame rate 75 kHz. The initial position and, thus, boundary conditions significantly influenced dynamics. first collapses showed distinct unidirectional extended jetting but without notch formation surface. Subsequent led intense nucleation, feature useful microfluidic devices. Further on, we observed vertical pillar-shaped cavities, floating toroids, etc., shapes rarely mentioned previous investigations. To support our experimental results, numerical simulations based solving Navier–Stokes equations, replicate similar Our results provided insight into thereby potentially contributing improved understanding pumping techniques, surface cleaning devices, fouling complex shapes, biomedical devices employing cavitation-based methods, and micromixing fluids. Results these experiments may serve also as benchmark data validate methods.
