For example, see Refs. Correlation and prediction of surface tension of highly non-ideal hydrous binary mixtures using artificial neural network. Surface tension of the binary liquid mixture of acetic acid and 1,3-dimethylbenzene. We are a community of more than 103,000 authors and editors from 3,291 institutions spanning 160 countries, including Nobel Prize winners and some of the world’s most-cited researchers. n Surface tension of the mixture (1) water; (2) acetic acid. It is suggested that this effect is associated with the loss of some of the smaller primary particles, which occurs as the concentration of polysilicic acid is increased and the pH allowed to change slowly during the reaction. For packed-bed absorber, the effective interfacial area is increased for the positive Marangoni effect. As shown from Figures 3–6, the removal amounts were always larger for the TEG solution with ethanol than without ethanol. Statistical Thermodynamic Model for Surface Tension of Aqueous Organic Acids with Consideration of Partial Dissociation. The average deviation is less than 1 %. HeadquartersIntechOpen Limited5 Princes Gate Court,London, SW7 2QJ,UNITED KINGDOM. The results showed that the effective area was larger for the positive system than that of the negative system due to the more stable liquid film. Surface Tension of Dialkyl Carbonates + (Alkanes or 1,4-Dimethylbenzene) and 1,4-Dimethylbenzene + Alkanes Binary Mixtures at T = 308.15 K. Zhiqiang Chen, Shuqian Xia and Peisheng Ma.

Furthermore, the temperature of the upward fluid was still higher than the ambient liquid in the surface, and then the surface tension gradient was formed to make the outward flow radial. On the other hand, the ethanol vapor was injected in the gas phase to discuss mass transfer difference between the additive adding in the liquid and gas phases. thin film.

The small disturbance analysis was adopted to deduce that the surface tension gradient resulted from the change of temperature, which was large enough to produce the cellular-type flow in the liquid convective cell that was heated from the bottom [4].
