The use of flowing liquid metal streams or "liquid
walls" as a plasma contact surface is a very attractive
option and has received considerable attention over the
past several years both in the plasma physics and fusion
engineering programs. A key issue for the feasibility of
flowing liquid metal plasma facing component (PFC)
systems, lies in their magnetohydrodynamic (MHD)
behavior. The spatially varying magnetic field
environment, typical of a fusion device can lead to serious
flow disrupting MHD forces that hinder the development
of a smooth and controllable flow needed for PFC
applications. The present study builds up on the ongoing
research effort at UCLA, directed towards providing
qualitative and quantitative data on liquid metal free
surface flow behavior under fusion relevant magnetic
fields, to aid in better understanding of flowing liquid
metal PFC systems.
