A Low Order Flow Network Model for Double-Wall Effusion Cooling Systems
International Journal of Turbomachinery, Propulsion and Power, 2022 The high pressure turbine nozzle guide vane of a modern aeroengine experiences large heat loads and thus requires both highly effective internal and external cooling. This can be accomplished with double-wall effusion cooling, which combines impingement,
