Thermodiffusion in multicomponent n-alkane mixtures
(Nature Research (Part of Springer Nature), 2017)
Compositional grading within a mixture has a strong impact on the evaluation of the pre-exploitation distribution of hydrocarbons in underground layers and sediments. Thermodiffusion, which leads to a partial diffusive ...
Microfluidic separation processes using the thermodiffusion effect
(Elsevier B.V., 2018)
The numerical and experimental results presented in this work show that a relatively small temperature gradient
(5K), has great potential to generate a separation in interesting mixtures for biological purpose. In fact, ...
Radiant waste heat recovery from steelmaking and glass industry
(Edp Sciences, 2019)
This paper tackles the problem of industrial waste heat recovery through an unexploited heat transfer mechanism: thermal radiation. Energy intensive industries have a considerable potential of unused radiant heat, which ...
Adaptive coatings based on polyaniline for direct 2D observation of diffusion processes in microfluidic systems
(Elsevier, 2016)
Microfluidic devices are poised to dramatically influence the future of the process industry. Therefore the understanding and proper evaluation of the flow and mixing behaviour at microscale becomes a very important issue. ...
Contact angle measurement for LiBr aqueous solutions on different surface materials used in absorption systems
(Elsevier Ltd., 2018)
Wetting surface is a very important issue for the design of absorption applications and heat exchangers. The contact angle is deemed essential in wettability studies; However, LiBr aqueous solution contact angle studies ...
Determination of the molecular diffusion coefficients in ternary mixtures by the sliding symmetric tubes technique
(AIP Publishing, 2014)
A new analytical methodology has been developed to determine the diagonal and cross-diagonal molecular diffusion coefficients in ternary mixtures by the Sliding Symmetric Tubes technique. The analytical solution is tested ...
Thermodiffusion in Ternary Mixtures of Water/Ethanol/Triethylene Glycol: First Report on the DCMIX3-Experiments Performed on the International Space Station
(Springer, 2018)
We report on thermodiffusion experiments conducted on the International Space Station ISS during fall 2016. These experiments are part of the DCMIX (Diffusion and thermodiffusion Coefficients Measurements in ternary Mixtures) ...
Sorption isotherm, glass transition, and diffusion coefficient of polyacrylamide/water solutions
(ACS Publications, 2012)
The sorption isotherm, the glass transition, and the mutual diffusion coefficient of polyacrylamide/water solutions are obtained experimentally. All of these parameters are measured in the concentrated regime by gravimetric ...
Determination of molecular diffusion coefficient in n-Alkane binary mixtures: empirical correlations
(ACS Publishing, 2012)
In this work we have measured the molecular diffusion coefficient of the n-alkane binary series nCi-nC6, nCi-nC10, and nCi-nC12 at 298 K and 1 atm and a mass fraction of 0.5 by using the so-called sliding symmetric tubes ...
Mass effect on the soret coefficient in n-alkane mixtures
(AIP Publishing, 2014)
We have determined the Soret coefficient of different equimolar and non equimolar n-alkane mixtures from measurements of the molecular diffusion and thermal diffusion coefficients. It is shown that equimolar mixtures behave ...
