| Abstract Scope |
Non-contact modulation calorimetry utilizes electromagnetic levitation in microgravity to investigate the thermophysical properties of metals at elevated temperatures. This configuration is accomplished by modulating the electromagnetic field, inducing changes in the power input to the sample and an out-of-phase temperature response. In liquid droplets, the fluid flow within the sample changes the internal temperature distribution due to magnetohydrodynamic convection and thermal conduction through the metal. However, measuring the sample’s internal flow directly is challenging because of the high temperature, reactivity, strength of the magnetic field, and the metal’s opaqueness. To model the droplet’s behavior, researchers must account for fluid flow when interpreting results. Thus, employing models that incorporate magnetohydrodynamics, fluid flow, and heat transfer is invaluable in data analysis. Current work is reevaluating historical data from the IML-2 TEMPUS to improve the model’s accuracy and performance, and in analysis of recent measurements from the International Space Station Electromagnetic Levitation Facility. |
