Abstract
In this contribution, Large Eddie Simulations (LES) are employed to analyze a combustion chamber operating at rocket-like conditions. Non-premixed turbulent combustion is handled through a flamelet approach, accounting for non-adiabatic, non-equilibrium effects. A compressible and a real-fluid formulation isimplemented to accurately simulate rocket-like operational conditions. The employed multi-physics, flexible framework is shown to correctly represent the main flame features of the transcritical flame, exhibiting a good agreement with the experimental results. Furthermore, two different thermal boundary conditions are analyzed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
