Abstract
The temperature fields of mercury flows in a vertical cylindrical tube located in a longitudinal magnetic field are investigated experimentally. The controlling parameters were varied over the following limits: Re = 7−50·10³, corresponding to the strongest effect of the longitudinal magnetic field on heat exchange; q = 0.5−3·10⁴W /m²; and Ha = 0−550. The coefficients of heat transfer and of turbulent heat transfer are calculated from the measured temperature profiles. The experimental results allow a more precise determination of the effect of a longitudinal field on heat transfer and indicate a significant reduction in the turbulent heat transfer coefficient in a magnetic field.
