Effect of wall suction on the transport of a scalar by coherent structures in a turbulent boundary layer
Abstract
Two kinds of measurements are described. In the vicinity of the wall the longitudinal heat flux is studied through the correlation coefficient and the joint probability density function; particular attention is paid to temperature measurements. Conditioned measurements based on the detection of temperature fronts are performed using a five cold-hot-wire arrangements. The influence of wall suction on the importance of coherent motions is investigated.
