Abstract
The heat exchange rate in a passage in indirect heat exchange with a fluid medium is tailored to match its temperature gradient by 'short circuiting' the flow in the passage to minimize heat transfer in regions requiring less heat exchange and maximizing heat transfer in regions requiring more heat exchange. The serpentine passageways of an air cooled turbine blade for a gas turbine engine is short circuited to match the temperature profile of the gas path passing by the blade.
