@@@@Graphic abstract A volume-average-based dendritic solidification model is used to analyse the solidification of NH4Cl – 70.43 wt.%H2O solution in a water-cooled mould with a large sample thickness (100 × 80 × 10 mm3). The modelling result (meandering flow) agrees with the experiment. (a) Experimentally measured flow pattern using the PIV technique; (b) simulation result of the velocity field; (c) density distribution of the liquid solution; (d) zoomed-in view of the flow field in and ahead of the mushy zone.
