The pressure drop increases with the mass flux increases.
在同一质量流量下,压力损失由大到小依次为DN6﹥DN8mm﹥DN10。 压力损失随雷诺数的增大而增大。
The results of numerical analysis show that for a given channel, mass flux in the channel does exist a maximum, so does those of the experiment. There exists thermal drag in natural convective boiling.
结果给出:通道内自然对流沸腾存在热阻力;存在抽吸质量速度极大值,实测也证明了这一点;质量速度达到极值点以后,随热流密度增加,迅速下降,对应着第三类沸腾危机的发生,这为第三类沸腾危机提供了新的解释。
And the velocity of liquid in the middle of where the space between the walls is bigger is smaller.3) The mass flux increases as the zeta potential, the electric field strength, the temperature of liquid, and the concentration of electrolyte.
③液体的质量流量随zeta电势、电场强度、流体温度及电解质浓度的增加而增加,随槽道尺寸的增加先增加后减小。
Global average CTF present remarkable characteristic of QBO,annual evolution of CTF is very obvious over Southern and Northern Hemispheres,in particular,the catastrophe of mass flux amplitude appears during the middle of 1970′s to the middle of 1980′s.
全球平均的CTF有显著的QBO特征,南北半球的年代际变化明显,特别是20世纪70年代中期至80年代中期出现了质量通量振幅的异常突变现象。
