LES Investigation of Film Cooling in Rotating Detonation Combustors

open access: yesVolume 7: Heat Transfer: Combustors; Heat Transfer: Film Cooling
Abstract High-power density combustors like Rotating Detonation Combustors (RDC) offer significant benefits. However, they must overcome many challenges to be integrated into a gas turbine. Cooling the RDC is one of the most significant, due to the high heat loads generated by the combustion process.
