...Kexin Liu; Qiang Zhang The impingement cooling for a modern gas turbine component, either a combustor liner or a high-pressure turbine blade, is often not as efficient as required due to strong cross-flow effect and coolant maldistribution. This paper reports a novel multi-stage impingement cooling...

...Kexin Liu; Qiang Zhang Cross flow and coolant maldistribution are the common design challenges for impingement cooling in modern gas turbine. This paper reports a novel multi-stage impingement cooling scheme for combustor liner. The design concept and general working mechanism are introduced...
