Heat Transfer During the Solidification of Eutectic PbSn Alloy Droplets in Drop Tubes

The study of heat transfer during the free fall of PbSn droplets is important to optimize the alloy solidification conditions in drop tubes. In this paper a model of heat transfer by conduction is applied in the solidification of PbSn eutectic alloys in a 3 m length drop tube installed at Associate...

Summary:The study of heat transfer during the free fall of PbSn droplets is important to optimize the alloy solidification conditions in drop tubes. In this paper a model of heat transfer by conduction is applied in the solidification of PbSn eutectic alloys in a 3 m length drop tube installed at Associate Laboratory of Sensors and Materials of the Brazilian Space Research Institute (LAS/INPE). Drop tubes are one of the most suitable and low cost options to provide a microgravity environment on the ground.
