Abstract

Two-dimensional simulations of laminar mixed convection in a square enclosure subjected to constant wall temperature with a heated rotating cylinder have been carried out. The enclosure is filled with non-Newtonian fluid. Due to the rotation of the cylinder, forced convection effects are set up along with the natural convection. The effect of different parameters, viz: Rayleigh number (103 to 106), and angular velocity on non-Newtonian fluid enclosed in a square enclosure are investigated. Observations are also made on the dynamic behavior of the flow features and temperature fields due to the rotation of hot cylinder inside a square enclosure. Overall, the present study focuses on how the rotating cylinder affects the thermo-fluid behavior of non-Newtonian fluids and quantifies heat transfer characteristics.
