Abstract: Aiding buoyancy flow and heat transfer phenomena of the dilatant (shear-thickening) fluids is examined for a square obstacle fixed in a vertical channel of confinement (?) = 25%–50%. The computer simulations are performed at various Reynolds numbers (Re = 1–40), Prandtl numbers (Pr = 1–50), Richardson numbers (Ri = 0–2), and power-law indices (n = 1–1.8). The output parameters and the illustrative isotherm and streamline patterns are obtained to clarify the function of various input parameters in the current framework. The maximum growth in heat transfer is ~ 993% for Pr = 50 (at Re = 1, n = 1, Ri = 2, ? = 50%) with the corresponding values at Pr = 1 (Re = 1, n = 1, Ri = 2, ? = 50%). Total drag coefficient and the Colburn heat transfer factor correlations have been achieved, in the end. © 2018 by Begell House, Inc.
