dc.description.abstract | The interaction of bubbles, both oscillating and stationary near biomaterials is of interest for the development of various medical treatment involving ultrasound and shock waves. This is because cavitation bubbles often nucleate in the bodily fluid under pressure waves, and their dynamics directly influence the success of the treatment and the collateral damages sustained. For example, in the treatment of Extracorporeal Shock Wave Lithotripsy (ESWL), cavitation bubbles are created when the shock wave is administered. These bubbles oscillate and collapse near the kidney stones and the body tissues. They are responsible both for the breaking up of the stones as well as the collateral damages to the nearby tissues. We study the interaction of an oscillating bubble near various biomaterials. The bio-materials are modeled as elastic fluids with similar physical properties such as elastic modulus, Poisson ratio, and density. The bubble dynamics are summarized based on biomaterial physical properties. We also study the interaction of a stationary bubble with the nearby bio-materials when hit by a lithotripter shock wave. High speed jets and splitting of bubbles are observed due to the influence of the nearby biomaterials. | en_US |
