Résumé :

In this contribution, the development and validation of a multi-region, multi-physics solver for turbulent combustion and Conjugate Heat Transfer in Liquid Rocket Engine relevant conditions are presented. The solver tackles simultaneously multiple solid and fluid domains, either mono-species or single-species, and enforces an interface condition guaranteeing temperature and heat flux continuity. Two different coupling strategies are developed and validated, making the solver amenable to the numerical simulation of industrial and laboratory time-scales. Results of the validation process are presented, based on several test cases each one devoted to a specific solver feature.
