Abstract
A structure for improving performance of cooling a blade of a gas turbine is provided in which interaction vortexes are generated between working fluid flowing along a surface of the blade and cooling fluid discharged onto the surface from an internal flow passage of the blade. The blade includes a surface structure formed by a gas hole having an outlet communicating with the surface of the blade to discharge the cooling fluid; and a vortex relief generator disposed so as to protrude from an inner periphery of the outlet and configured to generate counter vortexes having directionality opposite to the interaction vortexes so that the interaction vortexes are relieved by collision with the counter vortexes. The vortex relief generator includes a pair of opposing fins disposed in a path of the cooling fluid, each of which has a first surface to change a flow direction of the cooling fluid.
