Circular Acoustic Microstreaming Flows due to Pulsating Microbubbles near a Membrane Free

In this study, the microstreaming velocity near a plane wall due to microbubble pulsation has been studied. Microbubbles are assumed to pulsate spherically near the wall under the excitation of low amplitude ultrasound. It has been shown an axisymmetric vortex is generated near the wall inducing shear stress on the wall. The shear stress can help facilitate the uptake of drugs and genes in to desired cells through the process called sonoporation.
