Effusion and Skin Cooling for Micro Gas Turbines

As the power and thrust requirements from modern micro turbomachines increase, they pose new challenges on the thermal management of the units. As such, the turbines of these devices are operating in increasingly harsher thermal environments and as the micro turbine are currently mostly uncooled, new cooling paradigms have to be explored to further promote the state of the art. Therefore, we are using our turbine research facilities to develop effusion and skin cooling methods for micro gas turbines. Previously used only in their larger counterparts, the transition of these methods to smaller scales is not trivial and requires significant scientific and experimental inputs in order to provide viable cooling solution for micro turbines.
