Aerospace Instrument-Making Annotation << Back APPLICATION OF VORTICAL POWER DIVIDERS FOR THERMAL PROTECTION OF KNOTS OF HIGH-TEMPERATURE GAS AND STEAM TURBINES Sh.А. Piralishvili, I.V. Frolova, S.V. Veretennikov, S.М. Hasanov, S.А. Smirnov Possibility of increase of efficiency convectional cooling of nozzles of high-temperature gas and steam turbines of the combined power plants by application of swirling a cooler stream, with realization of effect of power division (effect of Rank) is considered. The analysis of efficiency of use of the swirled stream superheated water steam as a coolant for nozzles of high-temperature turbines is made. Keywords: Vortex cooling, Ranque effect, vane, cooling system, heat-transfer coefficient. E-mail: piral@list.ru
