Abstract
The low gravity (g) environment of space has the potential to produce conditions in which buoyancy driven convection is suppressed. This convection free environment can then be used to examine the influence of convection on various phenomena. Of significant interest to industry and the scientific community is how convection influences solidification processes. This interest is due to the complex relationship among thermal conditions, thermal and solutal convection, growth morphology, and macrosegregation in solidified alloy ingots and sensitive electronic materials [1,2]. Direct, quantitative analysis of convection in molten metals and semiconductors is particularly difficult. These materials are generally opaque, which hinders nonintrusive measurements. Thus, most studies are limited to indirect measurement techniques such as temperature and Seebeck measurements, Peltier pulsing and post-mortem analysis. The role of numerical modelling then becomes crucial in analyzing the system. A better understanding of how convection influences solidification can be achieved through synergistic numerical [3] and analytical modeling in combination with various solidification experiments on earth [4,5] and in space.
