Abstract

A set of experiments, featuring axisymmetric metallic melt spreading in presence of basal solidification, is presented. The influence of the basal crust onto (i) the position and flow structure of the hydraulic jump and onto (ii) the history of the moving (outer) contact line is discussed. We find that the growing basal crust is responsible for the hydraulic jump moving inwards, probably in conjunction with a change of the flow structure. The moving contact line tends to depart from a circular shape towards a fingering shape for a cooled substrate. Thus, the cooling of the substrate destabilizes the axisymmetric spreading.
