摘要：

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 mushy layer of homogenous permeability at the near eutectic (solid) 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 mushy layer.
