Abstract
The mechanism of pressure rise in a gas-liquid two-phase pipe flow of a magnetic fluid under a nonuniform magnetic field is investigated in detail both theoretically and experimentally. First, the governing equations of a one-dimensional gas-liquid two-phase flow of a magnetic fluid are presented and numerically solved. Next, the pressure distribution in a nonuniform magnetic field region is measured in the cases of two-phase flow, single-phase flow and the stationary state using a new experimental apparatus for the flow system. From the numerical and experimental results, the magnitude of the pressure components which contribute to the total driving force is accurately estimated. These results on the pressure distribution will contribute to the development of a new energy conversion system using a gas-liquid two-phase magnetic fluid flow.
