| Research Abstract |
An experiment on pool boiling on a circular copper surface in water was performed for a case in which the boiling space was restricted by an interference plate with many holes. The space between the heat transfer surface and interference plate was hermetically sealed at the perimeter to simulate a large surface of heat transfer. The vapor and liquid were thus exchanged through the holes. Many boiling curves were obtained for different conditions, and boiling appearance was observed for many patterns of holes on the interference plates. The following results were obtained.
(1) High heat flux was obtained in the narrow space at a small surface superheat of less than 1K.
(2) The interference plate of high heat transfer performance was found comparable to other heat transfer surfaces of high performance.
(3) In water, the best performance was given by an interference plate with holes of 4mm and 1mm in diameter when the plate was 0.12mm above the surface.
