Investigation of Film-Cooled Rough Surfaces Using Large Eddy Simulation
Краткое описание
In the present paper the effect of roughness on film cooling has been investigated numerically using Large Eddy Simulation (LES). A range of roughness parameters related to the momentum thickness of the crossflow boundary layer has been studied. A roughness element model is used for representing the microroughness over the film-cooled surfaces. Results for different roughness parameters are analyzed and compared with the baseline smooth case. Beyond 2 hole diameters of coolant injection, roughness is shown to reduce the cooling effectiveness.
