VISCOSITY MEASUREMENT USING BREAKUP OF A LEVITATED DROPLET BY ROTATION
Get access
SINOPSIS
Thermophysical property measurement without container is used for high-temperature molten material. A microgravity environment is useful in order to achieve a containerless condition, and the levitation technique can also be used for containerless processing even on the ground. The purpose of this study is to establish a new measurement technique to measure viscosity in the moderate viscous range, which has no conventional measurement methods. In this study, a droplet is levitated by electrostatic force and induced to rotate. The dynamic behavior of the levitated droplet shape is observed, and the viscosity measurement is obtained by using breakup of the levitated droplet depending on the viscosity.
