Abstract
In the present work, reactive rarefied gas flows over the SARA capsule were performed using the direct simulation Monte Carlo method. The main goal of this work is to access the influence of weakly ionised gas flows during the SARA reentry phase at 80 km altitude. In order to perform the chemical reactions the Quantum-Kinetic chemistry model was implemented into the dsmcFoam code. According to the results, the chemical reactions have a significant influence on the temperature reduction of the shock wave and flowfield structure surrounding the SARA capsule
