Title: Numerical investigation of the drag on a shock accelerated particle

Abstract

In this report, we summarize the work that was done in collaboration with the Extreme Fluids (EF) team from the Neutron Science and Technology group (P-23). The EF team, led by Dr. Katherine Prestridge, have performed a series of experiments of dilute microparticles being accelerated by an incoming shock. Their measurements of the location of the particles after being hit by the shock suggest that the particles experience a much higher drag than predicted by classical drag models. We performed fully-resolved numerical simulations using an immersed boundary technique to replicate the post-shock conditions around the sphere. Our results were more compatible with the classical drag model than the experimental measurements. The source of this apparent drag increase is still unknown.
