Numerical Modeling of Shock Induced Aerobreakup of a Droplet at High Reynolds and Weber Number

Abstract

Shock/droplet interactions have been the focus of numerous experimental and numerical investigations due to the importance of understanding droplet physics in many aerospace engineering applications. This paper presents a status update on current modeling efforts for simulating shock/droplet interactions (primarily in 2D) using the open-source NGA2-MAST framework ( https://github.com/desjardi/NGA2 ). 2D simulation results using NGA2 are compared to previously published numerical and experimental results for shock Mach numbers ranging from 1.18 to 2.50. This work will provide the foundation for future 3D modeling efforts of shock/droplet interactions with higher shock Mach numbers.
