Temperature fluctuations in a liquid metal magnetohydrodynamic flow in a horizontal inhomogeneously heated tube

The investigation of heat transfer characteristics during liquid metal flow in a horizontal tube with one-sided heating of the lower half of the tube is carried out. Experimental investigations are conducted using the mercury MHD complex of the Moscow Power Engineering Institute and the Joint Institute for High Temperatures, Russian Academy of Science, in the context of a long-term collaboration program. The characteristics of the averaged and fluctuation temperatures are considered in different sections over the length of the heating zone in the area of a homogeneous transverse magnetic field. The laminar liquid metal flow revealed the occurrence and development of a low-frequency quasi-harmonic temperature fluctuation with great intensity.
