从理论和实验两方面详细研究了非均匀磁场作用下磁性液体气液两相管流中压力升高的机理。首先，建立了一维磁流体气液两相流动的控制方程，并进行了数值求解。然后，利用一种新的流动系统实验装置，测量了两相流、单相流和静止状态下非均匀磁场区的压力分布。根据数值计算和实验结果，准确地估计了影响总驱动力的压力分量的大小。这些关于压力分布的结果将有助于开发利用气液两相磁流体流动的新的能量转换系统。
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.
