| Summary: | A study of uncertainty analysis was conducted on four key thermophysical properties of molten Platinum using a noncontacting
levitation technique. More specifically, this work demonstrates a detailed reporting of the uncertainties
associated with the density, volumetric thermal expansion coefficient, surface tension and viscosity measurements at higher
temperatures for a widely used refractory metal, Platinum using electrostatic levitation (ESL). The microgravity experiments
were conducted using JAXA’s Electrostatic Levitation Furnace (ELF) facility on the International Space Station and the
terrestrial experiments were conducted using NASA’s Marshal Space Flight Center’s ESL facility. The performance of these
two facilities were then quantified based on the measurement precision and accuracy using the metrological International
Standards Organization’s Guide to the Expression of Uncertainty Measurement (GUM) principles. |
