内容記述 | Microgravity conditions have advantages of measurement of the surface tension and the viscosity of metallic alloys by the oscillating drop method with an Electromagnetic Levitation (EML) device. Since under microgravity conditions the surface oscillation spectra have a single peak and an exponential decay of the surface oscillations, we can obtain the surface tension and the viscosity by analyzing the surface oscillation spectra. However, the surface oscillation spectra have many peaks in sometimes even under microgravity conditions. This is due to modulation of surface oscillation by the sample rotation. From the modulation of the surface oscillation, precise measurements of the surface tension and the viscosity are difficult. In order to obtain the precise surface tension and viscosity from the surface oscillation spectra modulated by the sample rotation, we propose an improved analysis of the surface oscillation spectra of electromagnetically levitated liquid droplet under microgravity conditions. We try to measure the precise surface tension and viscosity by the proposed analytical technique with the measured surface oscillation spectra obtained under microgravity conditions by the airplane parabolic flight. This approach is relevant for high temperature, reactive alloys such as Ti based alloys which can not be measured by the sessile and oscillating or rotating cup method. | |||||
