Laser-induced breakdown of an optically trapped nanoparticle is a unique system for studying cavitation dynamics. It offers additional degrees of freedom, namely the nanoparticle material, its size, and the relative position between the laser focus and the center of the optically trapped nanoparticle. We quantify the spatial and temporal dynamics of the cavitation and secondary bubbles created ...

The nonlinear and multi-factor-dependent characteristics of the hydrodynamic forces acting on the aft body of a supercavitating vehicle are investigated using computational fluid dynamics (CFD). The CFD model of natural supercavitating flow is first verified and validated upon the supercavitating flow around a cavitator in the shape of a circular disk. Then the model is used to simulate the sup...

This study presents a method based on carpet bombardment of immobilized cells with cavitating flows. For this, cancer cell lines are exposed to micro scale flows from the tip nozzle under effect cavitation microbubbles. The deformation as result bubbles differs one type another. Therefore, difference in upon exposure (carpet bombardment) acts valuable indicator for diagnosis. developed system i...

This study investigates the influence of roughness on hydrodynamic performance, especially for hub vortex—and, hence, vortex cavitation—of a benchmark propeller operating under uniform flow conditions using RANS method. The Schnerr–Sauer cavitation model is also used modelling and off blades. In order to include effects in numerical calculations, experimentally obtained functions were incorpora...
