EXPERIMENTAL STUDY OF CONVECTIVE HEAT TRANSFER WHEN LIQUID METAL FLOWS IN A PIPE IN A LONGITUDINAL MAGNETIC FIELD
Resumo
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.
