Heat Transfer in Turbines
Abstract
This report summarizes the studies in heat transfer and film cooling effectiveness performed under Contract F33615-76-C-2018. The purpose of these experimental and theoretical studies is to develop an indepth understanding of heat transfer and film cooling in gas turbines. A common experimental procedure is described for heat transfer measurements under isothermal wall conditions using fast response heat transfer gauges in tests conducted in a shock tunnel and a blowdown facility. The tests were conducted at flow and thermodynamic conditions modeling the operating conditions of advanced gas turbines. The configuration under study were single slot, single line of holes, double row of holes on a flat and curved plates, and double lines on an airfoil located in a cascade. The experimental technique was validated by long duration high temperature tests of an air cooled flat plate. Also described is an analytical study of the thermal and fluid mechanical evolution of a cooling film injected from a single line of inclined holes.
