Hyers, Robert W. Excitation Pulse Microgravity Electromagnetic Levitation CC-BY In oscillating drop experiments, surface oscillations in a molten sample are captured and analyzed to determine the surface tension and viscosity of a melt without the need to contact the liquid sample. In electromagnetic levitation, surface oscillations are initiated using an excitation pulse in the electromagnetic field. The variation in the electromagnetic force field drives rapid acceleration in the melt while also changing the flow pattern. During the quasi-static flow conditions prior to the excitation pulse, the flow displays a “positioner-dominated” flow pattern with 4 recirculation loops in the sample hemisphere. However, the accelerating flow of the excitation pulse transitions into a “heater-dominated flow” pattern in which there are only 2 recirculation loops in the sample hemisphere. 2023-10-05T02:03:35Z 2023-10-05T02:03:35Z 2023 Article Book https://link.springer.com/article/10.1007/s11661-023-07080-2 https://dlib.phenikaa-uni.edu.vn/handle/PNK/9463 en application/pdf Springer
