要約

Experimental investigation of liquid metal heat transfer in a horizontal heated tube in longitudinal and transverse magnetic fields (MF) was carried out. The experiment was approximated to conditions of heat exchanging channels of the TOKAMAK thermonuclear reactor. Heating was uniform along the length and, in the general case, non-uniform around the perimeter of the tube cross section. Temperature fields and velocity profiles, distributions of local and average heat-transfer coefficients, and statistic characteristics of turbulent fluctuations of temperature were measured. An appreciable effect of thermal gravity convection (TGC) on temperature fields and heat transfer in a horizontal tube was observed. Results of the effect of longitudinal and transverse magnetic fields differ greatly.
