Summary

WITH THE HELP OF HOLOGRAPHIC INTERFEROMETRY, THE LOCAL NUSSELT NUMBER AT THE SOLIDIFYING INTERFACE IS OBTAINED AT CHARACTERISTIC TIMES DURING THE EVOLUTION OF THE SOLIDIFICATION PHENOMENON. VISUALIZATION PROVED THAT THE TEMPERATURE AND FLOW FIELDS AT THE EARLY STAGES OF THE SOLIDIFICATION ARE NON-SYMMETRIC AND UNSTABLE. A BUOYANCY-DRIVEN PLUME DEVELOPS ON THE UNDERSIDE OF THE PIPE AND FLOWS DOWNWARD. THIS PLUME SWINGS CONTINUOUSLY ABOUT THE VERTICAL AXIS OF SYMMETRY OF THE SYSTEM AND AFFECTS THE SOLIDIFICATION PROCESS.
