The plate to duct height ratio was fixed at 0.429. Eight heated plates, placed along the bottom wall of the duct, were used as the heat transfer surfaces. The studies included three-component mean and fluctuating velocity measurements at duct cross-sections and near the heat transfer surfaces using laser Doppler velocimetry. The near-wall axial vorticities, turbulent kinetic energy and axial mean velocities were obtained from the measured veloci
