Boiling heat transfer behavior of lead-bismuth-steam-water direct contact two-phase flow

Popis výsledku v původním jazyce

The boiling heat transfer behavior of lead-bismuth (Pb-Bi)-steam-water direct contact two-phase flow was experimentally investigated. Experimental study was performed using Pb-Bi-steam-water direct contact boiling two-phase flow loop. The heat transfer rate was estimated from data of one-dimensional flow direct contact boiling of water in Pb-Bi. It is assumed in the analysis that film boiling occurs at the surfaces of a small water droplet after water is injected into hot Pb-Bi flow, because of the large temperature difference between water and Pb-Bi (i.e. 493 K and 733 K for injection water and Pb-Bi temperature, respectively). The heat transfer occurs between Pb-Bi and steam without phase change after all water completely evaporates. The overall heattransfer coefficient decreased with the superheat at low injection flow rate and was nearly constant for high injection flow rate.
