buoyancy tube

基本解释

It has been found that the buoyancy intensified convection heat and mass transfer for upwards flow in a vertical heated tube;
结果表明：浮升力使自下而上流过竖直加热圆管的对流传热和传质增强；
Therefore, the influence of centrifugal buoyancy on the heat transfer performance of tube-shell heat exchanger with swirling flow was not negligible.
故在有旋流存在的管壳式换热器中，离心浮力对换热器传热性能的影响不可忽视。

The experimental results indicate that free convection caused by the buoyancy in the heated tube with natural circulation has great influence on the heat transfer characteristics.
实验结果表明，自然循环工况下上升加热段内工质的物性变化及由浮升力引起的自由流动对对流传热特性有重要影响。
