Аннотация

This paper presents an experimental study of the heat transport in a turbulent magnetohydrodynamic (MHD) liquid metal duct flow.
Local turbulent flow quantities are measured by a traversable combined temperature-potential-probe. The simultaneous measurements of time dependent velocity and temperature signals facilitates the measurement of Reynolds-stresses and turbulent heat fluxes. The technical relevant integral quantities pressure drop and temperatures at the heated wall are evaluated and compared with results from conservative design correlations.
It is observed, that turbulent heat transfer is promoted by an increased shear at higher magnetic field although there is a generally damping effect by Joules dissipation on velocity fluctuations.
