Computational Simulation of Shock-Bubble Interaction, using a Front-Tracking/Ghost Fluid Method

A front tracking/ghost fluid method was used to simulate fluid interfaces in a shock–bubble interaction problem. The method captures fluid interfaces, using explicit front-tracking and defines interface conditions, using the ghost-fluid method. In order to demonstrate the accuracy and the capability tracking of the approach used, an air-helium and anair-R۲۲ shock-bubble interaction cases were simulated. The computational results were compared with reliable experimental and computational studies, showing close agreements.
