Investigation of Mixing Law Efficacy for Gaseous Hydrodynamic Simulations

What is it about?

The mixing of helium and sulfur hexaflouride are simulated in a shock tube with a variety of mixing laws which describe how the simulation performs the mixing. Despite the fact that a relatively weak shock occurred, meaning the mixing should be close to ideal, the physics driving the simulation are incomplete therefore leading to model form error of the shock properties.
