Multi-Scale Modeling of Shock-Droplet Interaction Within a Shock Tube

This effort presents a multi-physics, multi-scale approach to modeling the problem of shock-droplet interaction within a shock tube. The overall motivation of this study is to simulate a practical experiment that provides a similar mechanism that a rain droplet would experience when interacting with the bow shock of a reentry vehicle. The present work presents a multi-scale approach using a lower fidelity simulation of the entire shock tube to gain the boundary conditions of the test section, and provide a preliminary impact analysis while a higher fidelity simulation of the droplet explores phenomena such as breakup, cavitation, and evaporation.
