RT Journal Article ID 70a6b6eb48ab2ac8 A1 Kumar, Deepak A1 Dhiman, Amit Kumar T1 EFFECTS OF AIDING BUOYANCY AND CHANNEL CONFINEMENT ON THE FLOW AND HEAT TRANSFER OF DILATANT FLUIDS FROM A SQUARE OBSTACLE JF Computational Thermal Sciences: An International Journal JO CTS YR 2018 FD 2018-03-14 VO 10 IS 2 SP 121 OP 149 K1 Square obstacle; Aiding buoyancy; Dilatant fluids and Heat transfer enhancement. AB Aiding buoyancy flow and heat transfer phenomena of the dilatant (shear-thickening) fluids are examined for a square obstacle fixed in a vertical channel of confinement (β) = 25–50%. The computer simulations are performed at various Reynolds number (Re = 1–40), Prandtl number (Pr = 1–50), Richardson number (Ri = 0–2) and power-law index (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, β = 50%) with the corresponding values at Pr = 1 (Re = 1, n = 1, Ri = 2, β = 50%). Total drag coefficient and the Colburn heat transfer factor correlations have been achieved, in the end.
