从单个汽泡动力学着手定性地分析了影响微重力下流动沸腾中汽泡脱离的几个因素,提出了对汽泡脱离的一种理解:在一定工况条件下,如果已产生的汽泡在垂直于流动的方向上能够为新产生的汽泡持续提供足够空间,在平行于流动的方向上它又能随着两相流动及时地滑移开,即可以实现微重力下流动沸腾中汽泡的持续脱离,为微重力下核态沸腾的形成提供可能.
From a single bubble kinetics, qualitative analysis of several factors that affect bubble detachment in flow boiling under microgravity is proposed, and an understanding of bubble detachment is put forward. Under certain operating conditions, if the bubbles already generated, In the direction perpendicular to the flow of bubbles can continue to provide enough for the new space in the direction parallel to the flow along with the two-phase flow in a timely manner to slip off, you can achieve micro-gravity flow boiling steam The continuous detachment of bubbles provides the possibility of formation of nucleate boiling under microgravity.
