| Abstract | Average fluid-to-particle heat transfer coefficients were experimentally determined for spherical aluminium particles heated in carboxymethylcellulose solutions. Two situations were considered: a still particle immersed in a moving fluid, and a particle rotating in an otherwise stagnant fluid. Fluid flow rate, rotating particle velocity, particle diameter and fluid rheological properties were varied, covering a large range of the generalized Reynolds (0 to 801) and Prandtl (69 to 5358) numbers. Average heat transfer coeffkients ranged between 56 and 2612 Wlm’K. The results were compared with values predicted by published dimensionless correlations, showing that correlations based on a Froszling-type equation were more adequate. It was found that the contribution due to natural convection should be considered for proper correlation of the results at low Reynolds numbers. The results also show the importance of the fluid velocity profile. |
