Abstract
A film cooling apparatus with a cooling hole () in a component wall (). A first surface () of the wall is subject to a hot gas flow (). A second surface () receives a coolant gas (). The coolant flows through the hole, then downstream over the first surface (). One or more pairs of cooperating electrodes (---) generates and accelerates a plasma () that creates a body force acceleration () in the coolant flow that urges the coolant flow to turn around the entry edge () and/or the exit edge () of the cooling hole without separating from the adjacent surface (). The electrodes may have a geometry that spreads the coolant into a fan shape over the hot surface () of the component wall ().
