Papers by Keyword: Micro Gravity

Abstract: Under reduced or micro gravity, bubble dynamic behaviors in liquid melts or liquid solutions are important and common problems on optimizing many processes in space science and technology. Due to limited availability experiments under reduced or micro gravity condition, the studies in this area is still quiet fragmentary. For this reason, we develop two pairs of Helmholtz-Maxwell (H-M) coils, which can produce a uniform gradient magnetic field for the ferrofluid filled in a closed Hele-Shaw cell, so as to achieve reduced or micro gravity condition. Afterwards, we establish the multi-physics mathematic model to calculate the magnetic field and the gravity compensation rate, which shows a 30mm×40mm well-distributed region for 90% gravity compensation rate exists.
