Abstract
A turbine airfoil () includes a flow displacement element () occupying a space between a pair of adjacent partition walls () in an interior portion () of a generally hollow airfoil body (). The flow displacement element () includes an elongated main body () extending lengthwise in a radial direction and a pair of connector ribs () respectively connecting the main body () to pressure and suction sides () of the airfoil (). A pair of adjacent radial flow passes (--) of symmetrically opposed flow cross-sections are defined on chordally opposite sides of the flow displacement element (). The radial flow passes (--) conduct cooling fluid in opposite radial directions and are connected in series via a chordal passage () defined in the interior portion () between the flow displacement element () and a radial end face () of the airfoil body (), to form a serpentine cooling path ().
