DescriptionThis paper presents a low order simulation of a hypersonic shock tunnel experiment at the Calspan-University at Buffalo Research Center (CUBRC). In this experiment, a relatively low enthalpy flow is passed over a double cone geometry at a speed near Mach 12. Empirical data is taken and a higher order simulation of the experiment is also used for comparison. The present study compares the low fidelity data (first order spatial reconstruction) against the empirical and higher fidelity data (second order reconstruction) for this flow. A large difference in separation zone length is evident between the high and low order simulations when pressure and heat transfer are plotted. This confirms the dissipative nature of low order numerical schemes. An evaluation of chemistry models is made as well, comparing the Park model with Kang & Dunn’s. Little difference is observed between the low order Park results and the low order Kang & Dunn data. The Kang & Dunn model is chosen because it requires fewer computational resources.
