Combustioninstabilities are caused by the interaction of unsteady heat releases and acoustic waves. To mitigate combustioninstabilities, perforated liners, typically subjected to a low Mach number bias flow (a cooling flow through perforated holes), are fitted along the bounding walls of a combustor...
