Flow Control Characteristics of Gas-Magnetic Fluid Two-Phase Flow by the Application of a Magnetic Field

Abstract

The magnetic flow control characteristics of magnetic fluid two-phase slug flow in a vertical pipe was examined from measured void fractions and pressure drops together with the two-fluid model. The axial pressure distribution was primarily dominated by magnetic pressure rise and drop, and acceleration loss both of which depended on the axial distribution of void fraction. As the interaction between gas and liquid flows, the virtual mass force was remarkably large near the position of maximum magnetic field strength. The drag force acted on gas phase greatly due to large slip ratio which was caused by the magnetic force.
