Use of a slanting hot-wire to make measurements in an artificially roughened tube
Abstract
A single slanting hot-wire, in conjunction with a normal wire, can be used to determine all the components of the mean velocity and RMS values of the fluctuating velocities as well as the components of the Reynolds shear stress in a flow field of unknown direction. In addition, the flow direction can be determined from the measurements made by the two wires. The method was used to make measurements in a pipe roughened with circumferential rings where the flow field bends as it passes over and between the individual roughness rings.
