Fluid management technique using capillary, electrostatics force, and centrifugal force under microgravity condition

摘要

This paper describes gas-liquid separation and bubble removal technology using capillary, electrostatics and centrifugal force under micro-gravity condition. Two phase flow in micro-scale systems has some similarities with in microgravity, since flow behaviors are governed by capillary force. And bubble removal techniques for micro-gravity condition will be effectively applied to micro-scale systems, in which micro bubble moves too slowly in ground based gravity. The authors observed fluid behaviors in vane type surface tension tank and bubble movements by dielectrophoretic and centrifugal force in microgravity. It was shown that these techniques are feasible to fluid management under microgravity condition and micro-scale systems.
