Rayleigh-Taylor and Kelvin-Helmholtz instabilities of liquid metal surface and the use of liquid metal divertor for automatic disruption mitigation
利用統計を見る
Analysis of Rayleigh-Taylor and Kelvin-Helmholtz instability of the liquid metal free surface suggests that the heavy mass of tin can stabilize the surface instabilities during quiescent phases, while the light mass of lithium cannot. Therefore a lithium PFC requires Capillary Pore Structure (CPS), which makes it difficult to accommodate the heavy heat load in DEMO.
During the disruption, RT and KH instabilities and the current induced in the LM and the halo current in VDE may inject LM into the core, which can be used for automatic disruption mitigation, which could impede the generation of runaway electrons.
Use of magnetically-guided liquid metal PFC would protect the blanket surface from the plasma heat load, continuously condition the wall and also serve as automatic disruption mitigation.
