Dispersion measurements in a turbulent boundary layer
Abstract
An experimental investigation of mean temperature profiles downstream of a long heated wire normal to the flow in a wind tunnel is reported. RMS values, skewnesses, and probability distributions of temperature fluctuations were determined at two sections in the boundary layer. Probability distributions of pulse and gap widths of the (intermittent) temperature signal were also obtained. It was found that the normalized mean temperature profiles approached an asymptotic form, independent of the source (tagging wire) distance from the wall.
