Pulsating Flow of Liquid Metals in a Circular Pipe under a Transverse Magnetic Field

Abstract

A pulsating flow of liquid metal in a circular pipe under a transverse magnetic field is analysed numerically and experimentally. A numerical analysis is carried out under the assumpution of a parallel flow to the axis of pipe and the effects of Hartmann, Womersley, and magnetic Prandtl numbers on the velocity, the induced magnetic field, and others are made clear. In an experiment, the sectional mean velocity, peripheral mean shearing stress at the wall, and their phase-lags from the wave of pressure gradient are measured and compared with the results of numerical analysis.
