Abstract
A method for redirection of coolant flow is provided. The method includes an identifying step that identifies a hot spot on an exterior surface of a body of a component of a turbine system. A first parameter of the component indicates that a temperature of the exterior surface in the hot spot exceeds a threshold value. Another identifying step identifies a cool spot on the exterior surface. A second parameter of the component indicates that the temperature of the exterior surface in the cool spot is below the threshold value. A reconfiguring step reconfigures a plurality of cooling passages of the component to direct a portion of a coolant from the cool spot to the hot spot.
