Abstract
Two-dimensional simulations of laminar mixed convection in a square enclosure subjected to constant wall temperature with a heated rotating and oscillating cylinder have been carried out. The enclosure is filled with non-Newtonian fluid. Due to the rotation and oscillation of the cylinder, forced convection effects are set up along with the natural convection. Observations are made on the dynamic behavior of the flow features and temperature fields due to the rotation and oscillation of hot cylinder inside a square enclosure. The comparison between the rotating and oscillating cylinder on heat transmission has also been made. Overall, the present study focuses on how the rotating and oscillating cylinder affects the thermo-fluid behavior of non-Newtonian fluids and quantifies heat transfer characteristics.
