LES Investigation of Film Cooling in Rotating Detonation Combustors

Volume 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.

Improved understanding of combustor liner cooling

, 2009
Heat management is an essential part of combustor design, as operating temperatures within the combustor generally exceed safe working temperatures of the materials employed in its construction. Two principal methods used to manage this heat are impingement and film cooling.
