Abstract: The vaporization of microlayer is an important mechanism in boiling heat transfer. By increasing microlayer vaporization boiling heat transfer could be enhanced. A new method based on the above mechanism is proposed, i. e., to eject an inert gas into the bulk liquid, to enhance boiling heat transfer outside a tube. The experiments showed that the heat transfer coefficient could be improved remarkably with this method.
摘要: <正>在沸腾传热中,微层蒸发(Vaporization of microlayer)是热量传递的一个重要途径.微层蒸发是指沸腾壁面产生的气泡在生长过程中,与壁面之间形成极薄的过热液体微层(30~50μm),微层过热而向气泡内部蒸发扩散,同时从壁面吸收热量做为汽化潜热,
