Towards Binary Gas Mixture ZDES for Space Launcher Base Flow Prediction

Résumé

In order to improve space launcher base flow predictions, it has been shown that the thermodynamic properties of the propulsive jet had to be taken into account. To this end, this paper proposes an extension of a mono-species Navier-Stokes solver (FLU3M) to permit the simulation of inert bi-species flows. The extended framework is based on a six-equation finite volume formulation. The physical modelling and the different numerical methods implemented are first described and then validated on a set of test cases of growing complexity with successful RANS and ZDES bi-species simulations. The framework is then used to study a generic space launcher base flow.
