In one embodiment, a gas turbine engine turbine flow member is described that contains a passageway having a flow obstruction that forms a tortuous passageway for the passage of a cooling fluid. The flow obstruction can include flow structures disposed toward either side of the passageway. In one non-limiting embodiment a flow structure can have a V-shape, and in another non-limiting embodiment the flow structure can have an elongate shape. As cooling fluid flows through the passageway it is encouraged to flow up, down, and/or along portions of the flow obstruction.
