In this contribution we present a set of numerical simulations to describe and validate a framework for the simulation of mixing, combustion and wall heat transfer process in rocket-like conditions. Such framework is based on unsteady Reynolds averaged Navier Stokes (URANS) approach where turbulent combustion modeling is tackled by means of a non-adiabatic flamelet-based method. The latter provides a detailed chemical description of a non-premixed flame structure at a reasonable computational cost and allows for the inclusion of pressure-dependent effects. As a result the proposed framework is both amenable to low and high Mach number flows. Two-dimensional results show good agreement in terms of pressure and heat flux along the chamber wall compared with experiments. Moreover, preliminary result of the proposed framework envisaged in a Large Eddy Simulation (LES) context are presented.
