Calculation of the heat flux and pressure on the double cone surface in a high-enthalpy non-equilibrium air flow

Navier–Stokes computations of a high-enthalpy (~ 22 MJ/kg) air flow around a double cone are performed for conditions of experimental studies carried out at the Calspan University of Buffalo Research Center (CUBRC). The aim of this work is to use the experimental data in order to assess CFD capabilities. The present computations are based on one-temperature and multi-temperature approaches. The computations based on the multi-temperature approach employ recent (December, 2018) QCT-based models of dissociation of N2 and O2. Numerical results are in good agreement with the experimental measurements of the heat flux and pressure on the double cone surface. Our computational results are also compared to the computational results of other authors (Kianvashrad et al., 2018 and Hao et al. 2017), and reasonable agreement is observed.
