The effect of suction on the asymmetry and flattening factors in a heated cylindrical duct
Abstract
The isothermal turbulent flow in a heated porous tube is measured using a system of hot-wire anemometers. It is observed that the correspondence of the minimum values of the asymmetry factor and the variations of the flattening factor in cases, respectively, of longitudinal fluctuations of velocity and temperature, with and without suction, seems to indicate the presence of a region where the fluctuations take the form of harmonic wave trains.
