An experimental investigation of the transport characteristics of momentum and heat in a turbulent wake of a cylinder interacting with a turbulent boundary layer has been carried out (Figure 1). The cylinder was placed just outside the plate’s boundary layer. The von Karman street of vortices produced behind the cylinder interacted with the boundary layer downstream of x/D=10. Heat was supplied to the boundary layer flow by means of the line heat source shown. Simultaneous recording of the instantaneous values of temperature and two velocity components were performed using hot wire anemometry employing a triple-wire probe. Time variations of one Reynolds stress component and two turbulent scalar flux components were obtained directly from the experimental data, by digital post-processing.
