“…This choice will introduce further modification factors of (1 þ ffiffiffiffi ffi Ri p ) to define a modified Reynolds number. Indeed, it will be seen later that the preceding modified definitions of Re and Pr are very effective for developing predictive expressions of the Nusselt number in such situations as has been demonstrated in the previous literature studies [36][37][38]. Suffice it to say here that the fluid mechanical aspects are examined in terms of the streamline contours, morphology of the yielded and unyielded sub-regions and drag coefficients (C D , C DP ).…”

Mixed-convection flow and heat transfer of non-Newtonian power-law fluids over a pair of side-by-side circular cylinders in aiding buoyancy are investigated numerically. The calculations are performed in an unconfined domain for the following range of physical control parameters: Reynolds number (Re) = 1−40, Richardson number (Ri) = 0−1, and power-law index (n) = 0.2−1 for a transverse gap ratio of 1.5 at a constant Prandtl number (Pr) of 50. Extensive numerical results are presented, such as viscous, pressure, and total drag coefficients, average Nusselt number, and transition from a steady to a timeperiodic regime. The overall drag coefficient and its components decrease with the Reynolds number and increase with the Richardson number for all values of the power-law index considered. The average Nusselt number increases with an increase in both the Reynolds and Richardson numbers but decreases with an increase in the power-law index. It is observed that aiding buoyancy and shear-thinning tendency augment heat-transfer characteristics. The maximum enhancement in heat transfer is found to be approximately 85% for Re = 40, n = 0.2, and Ri = 1. However, the maximum enhancement in the value of the average Nusselt number for Ri = 0 and 0.5 is found to be approximately 70% and 81%, respectively. Finally, a simple heat-transfer correlation is obtained for the values of Re, n, and Ri covered in this study.
