Abstract
This work is about experimental investigation of liquid metal mixed convection characteristics in a vertical pipe affected by strong transverse magnetic field. Influence of thermo-gravitational convection in non-isothermal flows of liquid metal affected by magnetic field is significant. Under certain conditions and configurations of the MHD heat transfer thermo-gravitational convection can cause low-frequency temperature fluctuations with abnormally high intensity.
The RK-3 loop (HEattransfer Liquid Metal Experimental Facility (HELMEF)) was designed and put into operation for heat transfer and hydrodynamics investigations during previously unstudied ratios of flow parameters such as Reynolds, Hartman, Grashof numbers, wherein temperature, velocity and their statistical characteristics are measured. New experimental data was obtained and processed by reconstruction of temperature fields and fields of temperature fluctuation characteristics.
Modes with low frequency fluctuation of temperature have been studied using new experimental facility and compared with previous results. The boundaries where low frequency temperature fluctuations decay in a strong magnetic field are found and studied for the first time.
