Buoyancy effects in vertical rectangular duct with coplanar magnetic field and single sided heat load - Downward and upward flow

The effects specific for downward and upward flows of liquid metal (LM) in a vertical rectangular duct in a coplanar magnetic field (MF) are investigated. The experiments were performed in the JIHT's test facility with a closed magnetohydrodynamic (MHD) mercury loop. The temperature and velocity fields were measured in the duct with single-side heating in a coplanar magnetic field. The averaged temperature fields, wall temperature distributions, statistical characteristics of temperature fluctuation and longitudinal velocity profiles were obtained. The results for the downward and the upward flow under different flow conditions are compared.
