| Abstract Scope |
Viscosity measurements of metallic samples obtained from electromagnetic levitator experiments on the International Space Station have traditionally exhibited deviations of over 10% for very viscous samples. This study presents a recalculation of the original data using a more detailed theoretical equation, resulting in improved accuracy with deviations reduced to approximately 2% [1]. The enhanced model accounts for previously neglected factors affecting levitation dynamics and electromagnetic forces, enabling more precise interpretation of experimental results. These recalculated findings provide a more reliable basis for understanding the viscosity behaviour of metallic melts under microgravity conditions. The improved accuracy contributes significantly to materials science research and supports future experimental design in space-based levitation studies. [2]
