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. This report covers the following aspects of the boiling in confined space: (1) Analysis of single phase forced convection in support plate crevices; (2) Analysis of convective boiling and dryout in support plate crevices; (3) Experiments of boiling and dryout in annular crevices with closed bottom; and (4) Experiments of convective boiling and dryout in annular crevices.
