Numerical Investigation of High Pressure CO₂-Diluted Combustion Using a Flamelet-based Approach

An efficient modeling framework for wall heat flux prediction in rocket combustion chambers using non adiabatic flamelets and wall-functions

“…The injector channels are not included in the computational mesh as also done in the LES simulations by Zips et al [31]: inlets are therefore patched at the faceplate and adiabatic conditions are imposed on the post-tip and the plate walls; a temperature profile extracted from the experiments is applied over all the chamber walls as a boundary condition. All the simulations are performed in the context of a modified version of the open source software package OpenFOAM [70], implementing the models previously described and already employed in previous works [43,44,50,71,53,72]. The pressurebased PIMPLE [73] solution algorithm is used to handle the pressure-velocity coupling.…”
