Abstract
A gas turbine of the type having cooling air supplied to cool the outer surfaces of the shrouds of the turbine vanes is provided with roughness elements disposed upon the outer surfaces of the shrouds. The roughness elements enhance the heat transfer characteristics of the shroud by increasing the surface area of the shroud and enhance the efficiency of the cooling air by increasing the turbulence between the cooling air and the shroud.
