ABSTRACT

The stability of the flow of interstitial liquid in a rotating mushy layer driven by expansion or contraction upon solidification is presented. A truncated system of governing equations corresponding to the near-eu-tectic limit is analyzed and the key mechanisms controlling the stability are identified. It is found that rotation stabilizes the flow driven by expansion upon solidification.
