Developing laminar mixed convection with solidification in a vertical channel

摘要: Solidification of both high and low Prandtl number fluids (n-octadecane aluminum) is considered for downward, mixed convection in the entrance region between vertical parallel plates symmetrically cooled below fusion temperature. A continuum model used to formulate a set steady, two-dimensional parial differential equations, which include influences axial diffusion thermal buoyancy. The equations are solved using fully elliptic, control-volume-based-finite-difference scheme. Results reveal that, given phase change system, conditions uniquely determined by Grashof-to-Reynolds ratio, Gr/Re, Peclet Pe, characteristic dimensionless Limiting cases involving large small values Pe have been considered, effect Gr/Re on thermally induced flow reversal fluid core has determined.
