Abstract
An airfoil () includes at least one internal cooling channel (A-F) extending in the radial direction and adjoined on opposite sides by an airfoil pressure sidewall () and an airfoil suction sidewall (). An internal surface () of the airfoil pressure sidewall () and an internal surface () of the airfoil suction sidewall () define heat transfer surfaces in relation to a coolant flowing through the internal cooling channel (A-F). A flow splitter feature () is located in a flow path of the coolant in the internal cooling channel (A-F) between the pressure and suction sidewalls (). The flow splitter feature () is effective to create a flow separation region downstream of the flow splitter feature (), whereby coolant flow velocity is locally increased along the internal surfaces () of the pressure and suction sidewalls ().
