Natural convective heat transfer of lithium under magnetic field

摘要

The magnetohydrodynamic (MHD) effect on a natural convection heat transfer of liquid metal lithium was experimentally studied. The test section consisted of a lithium pool and, a heater pin, which was settled in the center of the pool. The results are summarized as follows, (1) with increasing B (Ly≥50), the Nusselt number decreased to 70 of the highest value at 0.05 T of the magnetic field; (2) large scale circulation flow profile and temperature profile were found to change drastically with the application of the weak field of 0.01 T.
