Popis:	The effectiveness of using steam for cooling the first-stage nozzle vanes, one of the most thermally stressed components of gas turbines, is analyzed. Results obtained from calculation of the designed vane furnished with a cyclone-vortex cooling system carried out in the ANSYS CFX software package are presented. It is shown that use of steam in combination with flow swirling in the cooling system channels makes it possible to achieve essential enhancement of heat-transfer processes and better efficiency of cooling averaged over the vane profile.
