Marangoni convection within thermosolute and absorptive aqueous LiBr solution
2022, International Journal of Heat and Mass TransferCitation Excerpt :The analysis of the influence of solid objects still needs to be studied more deeply, because in this case, the free surface deformation and contact angle effects are neglected. As far as we know, the results of this proposed method have never been discussed in a published paper journal, but the present results are quite reasonable because of providing better agreement with the experiment [4] compared to the previous calculation [4] as shown in Fig. 36. The comprehensive study on the Marangoni convection during steam absorption into an aqueous LiBr solution is investigated numerically.
Experimental and theoretical investigation on the surface tension of nano-Lithium Bromide solution

2020, Chemical Engineering ScienceCitation Excerpt :But in their theoretical description, the wavelength was considered to be a known value that must be obtained experimentally. In 1997, Daiguji et al. experimentally observed the influence of the Marangoni effect during the falling film absorption with aqueous LiBr (Daiguji et al., 1997). Then, Karami and Farhanieh (2009, 2011), and Hofmann and Kuhlmann (2012) found that waviness is a key factor in enhancing the efficiency of mass transfer in water–LiBr absorbers.

2019, Applied EnergyCitation Excerpt :However, the trigger mechanism for Marangoni convection is still unclear. Some possible theories, such as the Kashiwagi model [151], the salting-out model [148], the solubility model [152] and the vapour surfactant theory [153], have tried to give a reasonable interpretation for the trigger mechanism. However, they can only partly explain the experimental phenomenon; their explanations are not applicable for all experimental observations.
Experimental investigation of heat and mass transfer in a LiBr-H<inf>2</inf>O solution falling film absorber on horizontal tubes: Comprehensive effects of tube types and surfactants
2019, Applied Thermal EngineeringCitation Excerpt :Marangoni convection was observed in falling film of LiBr-H2O solution, which resulted in significant enhancement of heat and mass transfer by more than two times through the application of 2-ethyl-1-hexanol. Daiguji [17] investigated the Marangoni effect based on the salting out effect. By LiBr absorption experiments with surfactants, Kulankara [18] proposed that the surfactant in vapor affects the surface tension of LiBr-H2O solution.
