摘要

The paper presents the experimental results of the effect of a longitudinal magnetic field on convective heat transfer when liquid metal flows in a pipe. Experiments were carried out in a set-up with a closed liquid-metal loop. The pipe 2.0 m long was installed along the axis of a water-cooling solenoid designed to generate a uniform longitudinal magnetic field over a length of about 1.0 m. Temperature and velocity distributions over the pipe radius were determined at Reynolds number Re = 25,600 and Peclet number Pe = 1412. Measurements were made with hot-wire anemometer. Besides the data were defined - variations of Nusselt number, temperature fluctuation intensity, temperature fluctuation spectrum and temperature autocorrelation coefficient with Hartmann number. The measurements were made at Hartmann number values - 0, 150, 277, 515, 880, 1315. Presented experimental data display the significant influence of a longitudinal magnetic field on the flow and the intensity of convective heat transfer.
