Large Eddy Simulation Modeling of Heat Flux in a Rotational Detonation Engine

This study investigates the heat flux distribution within a Rotational Detonation Engine (RDE) using Large Eddy Simulation (LES) to capture the complex turbulent flow and combustion dynamics. The focus is on modeling heat flux patterns, particularly near the engine walls, where intense detonation-induced heat transfer poses significant challenges for thermal management. By employing LES, we provide detailed insights into the various heat flux components, including conductive, convective, and diffusive heat fluxes, and their distribution within the combustion chamber. The results highlight the limitations of 2D models and emphasize the necessity of 3D simulations for accurately predicting heat fluxes, offering critical guidance for future thermal management strategies in RDEs.
