Abstract
The life of a downstream part disposed in a hot gas stream having a cooling medium injected into the stream through multiple orifices in a first upstream part is enhanced by changing the location, configuration or direction of flow of the cooling medium through the orifices. This change alters the temperature distribution of the flow field, affecting the second downstream part thereby enhancing its life. Properties of the cooling medium may also be changed, i.e., temperature and/or mass flow, to alter the temperature distribution of the flow field affecting the second downstream part to enhance its part life.
