Studies on physical processes in divertor plate of free-surface liquid-lithium
Description
A comprehensive physical model including high temperature liquid lithium evaporation, expansion motion of lithium vapor, shielding effects of vapor cloud on incoming plasma particles and photon radiation and transport in the lithium vapor cloud plasma has been presented. A formula to describe the temperature-dependent evaporation power is derived. The maximum temperature rises of stationary liquid lithium surface target plate are compared under the intense deposition of energy (10 MJ/m2) over short period (1 ms) for considering or not considering evaporation processes respectively. The results show that large amount of surface heat load can be removed even by stationary free-surface liquid-lithium target plate due to rapid evaporation. The energy depositions of incoming high-energy particles and weekly relativistic electrons from SOL are calculated
