Title: Flow and heat transfer of an electrically conducting fluid in a pipe in the longitudinal magnetic field of a finite length solenoid

Abstract

One of the most promising modern power generation development directions is directed towards the realization of a controlled thermonuclear reaction in TOKAMAK type reactors. Intensive investigations are currently underway to select a suitable heat transfer agent to remove the heat from the TOKAMAK blanket. In one of the investigated variants, the use of a liquid metal as the heat carrier is envisaged. It is obvious that the choice of the final blanket variant in many ways is determined by the reliability and completeness of its thermophysical substantiation. When a liquid metal flows through strong magnetic fields that are characteristic of the TOKAMAK blanket, numerous problems arise, which are related to the flow interaction with the magnetic field. Thus, in the flow in a perpendicular magnetic field, the hydraulic resistance may increase significantly. This is linked to an increase in the pumping energy consumption and an excessive pressure rise in the loop. In this plan, the case, where the fluid flow is oriented along the magnetic field lines of force is significantly more favorable. When the flow is in a longitudinal magnetic field, there is no Hartmann effect which is linked to a flattening of the mean velocity profile, and themore » magnetic field action is only responsible for suppressing the turbulent fluctuations. This leads to reductions in the hydraulic resistance and in the heat transfer.« less
