摘要
Abstract
To study the effect of the rolling motion on the sub-cooled boiling heat transferring characteris⁃tics in a vertical narrow channel, a bubble dynamic mathematical model is established in this paper, and the effect of the force variation on the sliding bubble under both static and rolling motion conditions is cor⁃respondingly investigated. In addition, based on the separation flowing model, the degree to which the roll⁃ing motion affects the sub-cooled boiling fluid thermal-hydraulic characteristic and bubble dynamics is studied theoretically and experimentally. The results show that when the mass flux does not pulsate evident⁃ly with the rolling motion, the additional force induced by the rolling and the variation caused by the buoy⁃ancy force can not lead to prominent change of bubble motion, either. Therefore, the influence of the rolling motion on the sub-cooled boiling heat transferring characteristic can be treated as negligible, and the ob⁃tained results can be treat as reference for ship-based heat exchanger capability evaluation.关键词
