Heat flux measurements in homogeneous curved shear flow

Turbulent heat fluxes It ere measured far downstream of a fine heating wire stretched spanwise across a curved, uniform shear flow The turbulence,cas approximately homogeneous and the overhear small enough to be passive. Strong destabilizing and stabilizing curvature effects were produced by directing the shear toward the center of curvature and away from the center of curvature, respectively. The dimensionless turbulent shear stress was strongly affected by the flow curvature, but the dimensionless components of the turbulent heat flux were found to be relatively insensitive.
