Experimental and Theoretical Investigations of Flowfields and Heat Transfer in Modern Gas Turbines

Abstract

Aerodynamics and heat transfer of high pressure turbines were studied computationally and experimentally. Two- and three-dimensional steady, and two-dimensional unsteady viscous codes were written. An 0.3 second duration, full rotating stage, test rig was built and instrumented to yield both steady state and time-resolved data. The CFD solution and experimental data were in good agreement. The rotating rig data resembled that from cascades rather than full scale engines. Keywords: High pressure turbine stages.
