Fully Resolved Simulations of Air-Shock Interacting with Randomly Distributed Spherical Particles
ORAL
Abstract
Shock particle interaction is a fundamental problem in many engineering applications, with the dynamics being heavily influenced by the incident shock Mach number and the particle volume fraction. We vary the strength of the incident shock along with the particle volume fraction in order to study the complex wave interaction during shock particle interaction. Mean of flow properties like pressure, density and velocity were computed to characterize the strength of the various waves occurring during shock particle interaction. The random distribution of particles results in velocity and pressure fluctuations. We compute the pseudo turbulent Reynolds stress along with the turbulent kinetic energy to understand their importance during shock particle interaction.
