Abstract
A combined experimental and numerical study is reported of dendritic solidification of an ammonium chloride-water solution inside a vertical rectangular enclosure. Based on the volumetric averaging technique, one set of conservation equations is derived, which is valid for the liquid and solid regions as well as for the dendritic mushy zone. Experiments are performed to visualize the phase-change and convection processes in the cavity. It is found that the solidification process induces a variety of double-diffusive phenomena in the liquid, including plumes and layering. These convection processes influence considerably the local solidification rates and can cause remelting in parts of the system.
