MHD pressure drop of lithium single-phase flow and helium-lithium two-phase flow in a circular channel

摘要

In order to confirm the effectiveness of a helium-lithium annular two-phase flow for the reduction of magnetohy- drodynamic (MHD) pressure drop in a liquid metal single-phase flow in the cooling of the first wall and blanket of magnetic-confinement fusion reactors, the characteristics of MHD pressure drop were investigated experimentally for a lithium single-phased flow and a helium-lithium two-phase flow in a horizontal electrically thin conducting circular channel in the presence of a uniform transverse magnetic field.
