Abstract
Laminar natural convection heat transfer in three-dimensional molten Lithium filled differentially heated enclosure, rotating about the vertical ridge is studied numerically. Computations are performed for a wide range of dimensionless parameters including the rotational Rayleigh number, and Taylor number while the values of Rayleigh number and Prandtl numbers are maintained constant at Ra=2×104 and Pr=0.0321, respectively. The results indicate that Coriolis forces seem to have a dominant role to suppress the thermal buoyancy driven effects. Transverse velocity isovaleurs show three-dimensional characteristics of the flow. By increasing, the Taylor number, the maxima of heat transfer gradually reduced about 55%. In the contrast, high rotational Rayleigh number values are found to significantly alter the flow patterns by increasing mixing which turn enhances the heat transfer.
