Liquid metal plasma facing components (PFCs) have been identified as an alternative material for fusion plasma experiments. The use of a liquid conductor where significant magnetic fields are present is considered risky, with the possibility of macroscopic fluid motion and possible ejection into the plasma core.
Analysis is carried out on thermoelectric magnetohydrodynamic (TEMHD) forces caused by temperaturegradients in the liquid-container system itself in addition to scrape-off-layer currents interacting with the PFC from a diverted plasma. Capillary effects at the liquid-container interface will be examined which
govern droplet ejection criteria. Stability of the interface is determined using linear stability methods.
In addition to application to liquid metal PFCs, thin film liquid metal effects have application to current
and future devices where off-normal events may liquefy portions of the first wall and other plasma facing
components.
