ABSTRAKT

The linear stability theory is used to investigate analytically the effect of a permeable mush-melt boundary condition on the stability of solutal convection in a rotating mushy layer of homogenous permeability at the near-eutectic limit. The results clearly show that in contrast to the impermeable mush-melt interface boundary condition, the application of the permeable mush-melt interface boundary condition destabilizes the convection in a rotating mushy layer.
