Neither the influence of high shear rates nor the impact of cavitation on protein aggregation is fully understood. The effect of cavitation bubble collapse-derived hydroxyl radicals on the aggregation behavior of human serum albumin (HSA) was investigated. Radicals were generated by pumping through a micro-orifice, ultra-sonication, or chemically by Fenton's reaction. The amount of radicals pro...

In the course of most recent decades reduction ship resistance and saving fuel consumption to accomplish higher speed with pollutants has been significant subject for researchers. Micro bubble drag technique is one interesting thoughts in this field owing its great advantages, such as considerable potential reduction, easy operations, environmental friendliness low costs. study a 3-D numerical ...

In the present work, a diffuse interface model has been used to numerically investigate laser-induced cavitation of nano-/micro-bubbles. The mesoscale approach is able describe process in its entirety, starting from vapor bubble formation due focused laser energy deposition up macroscopic motion. particular, simulations show complete and detailed description subsequent breakdown wave emission w...

Cavitation jet drilling has been extensively employed for the exploitation of geo-energy resources. The dynamics cavitation bubbles in close proximity to solid boundary have a subject great interest during drilling, as they play crucial role determining performance. In present work, single bubble near surface is numerically investigated by using axisymmetric Navier-Stokes equations and volume f...
