摘要
本文提出了从管束下部通入同种及异种气(汽)体强化水平管束沸腾传热的新方法,并进行了实验研究。沸腾工质为F-113,同种汽体为F-113蒸汽,异种气(汽)体分别为空气和水蒸汽。结果表明:管束的传热系数明显提高。特别是通入异种不凝性气体(空气)时,沸腾传热得到很大的强化。
A new method, which was to input bulk vapar or unsolvable Vapor/gas into liquid bulk below bundles, was presented for the enhancement of boiling heat transfer in tube bundles. The method was tested experimentally with F-113 as a bofling liquid, F-113 vapor as bulk vapor, and water/ air as unsolvable vapor/gas. The results shewed that the heat transfer coefficients of the tube bundles were improved greatly. In special, unsolvable gas enhanced the beiling heat transfer sharply.
