Published in: Numerical Heat Transfer; Part A: Applications
Abstract: The influence of opposing-buoyancy mixed convection from a square cylinder in a vertical channel has been studied at Reynolds numbers (Re) = 1-100, Richardson numbers (Ri) = 0 to -1, and blockage ratios (?) = 10-50% for air as a working fluid. The onset of a steady to a time-periodic regime is found for Ri = 0 (at Re = 35, 65, 74, and 62), Ri = -0.5 (at Re = 12, 39, 48, and 54), and Ri = -1 (at Re = 9, 30, 39, and 50) for ? = 10%, 25%, 30%, and 50%, respectively. The initiation of flow separation is also determined. Finally, the correlations of Strouhal number, drag coefficient, and the Colburn heat transfer factor were obtained. © 2016 Taylor & Francis Group, LLC.
