Boiling Heat Transfer in Confined Space.
Abstract
In many equipments, boiling occurs in confined space such as the clearance between the tube and the support plate of steam generators. Corrosive concentration builds up at the boundary of dryout zone and induces severe damage. The knowledge on this kind of boiling phenomena is very limited. It is the objective of this research to understand this fundamental heat transfer of this problem through systematical analysis and experimental studies. The forced convective two phase flow and boiling heat transfer in confined space is studied using the subchannel analysis which is an approximated method but effective in two phase calculations. Reasonable prediction of the dryout phenomena has been achieved. A separate analysis is performed for single phase flow heat transfer. This differential analysis is formulated from the lubrication theory and calculations are performed for both the line-contract or two-point contact configurations. Finally, the progress in experimental research is also reported here. (Author)
