分析了凝固时膨胀或收缩驱动的糊状层中间隙液流动的稳定性。完整的扰动方程减少在一个特定的渐近极限，允许控制不稳定的主要机制被确定。与多孔岩石中的酸蚀不稳定性进行了比较。然后求解完整的方程，以确定不稳定性的参数依赖性。据发现，虽然潜在的不稳定性存在，它是不太可能发生在实践中。
The stability of the flow of interstitial liquid in a mushy layer driven by expansion or contraction upon solidification is analysed. The full perturbation equations are reduced in a particular aymptotic limit that allows the principal mechanisms controlling instability to be identified. Comparisons are made with the acid-etching instabilities in porous rocks. The full equations are then solved to determine the parametric dependences of the instability. It is found that, though the potential for instability exists, it is unlikely to occur in practice.
