Abstract Scope |
Viscosity of selected alloys are measured using ISS-EML facility on the International Space Station. Through oscillating droplet method, the damping behavior of pulse induced surface oscillation of electromagnetically levitated molten samples are characterized and used to determine the apparent eddy viscosity and molecular viscosity based on the internal flow conditions. Experiment parameters are further optimized by assigning appropriate pulse amplitude and testing temperature allowing more effective viscosity measurement using the ISS-EML facility in microgravity conditions. |
