【摘要】 根据汽泡动力学原理,建立了壁面上沸腾汽泡的数学模型.分别计算了在不同重力条件和不同壁面流动条件下的汽泡特性参数,包括汽泡的脱离直径和鼓泡频率.比较了重力和强迫对流对汽泡特性的影响.提出了一种比较微重力条件和地面条件下核态沸腾的类比关系式,这一关系式对于将地面沸腾实验结果类比到空间微重力条件下具有一定的指导意义.更多还原

【Abstract】 A model of the boiling bubble was presented based on the bubble dynamics.The characteristics of the boiling bubble were studied under both various gravity conditions and various conductive conditions.The departure diameter and the bubbling frequency of the bubble were obtained.The effect of gravity condition and of conductive condition on the characteristics of the boiling bubble was compared.A correlation between the effect of gravity condition and of conductive condition on the characteristics of the boiling bubble was then concluded.With this correlation,the experimental results of the bubble boiling under the terrestrial condition could be extended analogously to instances under the space condition.更多还原
