Gurinov A. Improvement of the air and steam cooling systems for high temperature gas turbines

The research object - processes of heat exchange in running part of gas turbine and in the channels of the systems of cooling. Purpose - perfection of the systems of cooling of gas turbines by a way due to more exact determination of scope terms in a shoulder-blade vehicle, and also due to application of alternative coolers in the cooling system of gas turbines. The methods of research - the methods of theory heat exchange and hydrodynamics of boundary layer, methods of theory heat exchange and hydrodynamics in the channels of the cooling systems gas turbines for monophase and diphasic coolers. Scientific novelty - the method of determination of scope terms of heat exchange from the side of gas on butt end surfaces for nozzle and working blades is developed, efficiency of the use of steam in the system of cooling of gas turbines is grounded, the attended method of determination of gas dynamic descriptions of cooler and temperature state of the cooled elements of gas turbine is developed at the use as acooler in the system of cooling one and diphasic coolers. Results - possibility of the use at creation of the systems of cooling of high temperature gas turbines: software mathematical and for determination of local values of heat emission on the butt end surfaces of shoulder-blade vehicles, offered recommendations on replacement of cooling air on steam in the ramified systems of cooling. The degree of implementation - has been developed by Turbine Machinery Department of NTU "KhPI", OJS "Actual mechanics"; Application area - the field is turbine machinery.
