Abstract

The aerodynamics of a coolant jet in a hot crossflow in an environment representative of the gas turbine practice, is numerically investigated for film cooling applications. The time-dependent, mass-averaged Navier-Stokes equations coupled with the compressible form of a two-equation low-Reynolds number (k-ɛ) model are solved based on an explicit finite volume formulation. The computed flow-field and surface temperature distributions along with the turbulence quantities are presented to illustrate the variation of flow-physics and heat transfer phenomena which occur in a jet-crossflow interaction with changing blowing rates, slot angles, and inlet free-stream turbulence levels.
