The Soret coefficients of the ternary system water/ethanol/triethylene glycol and its corresponding binary mixtures
(Springer, 2021)
Thermodiffusion in ternary mixtures is considered prototypic for the Soret effect of truly multicomponent systems. We discuss ground-based measurements of the Soret coefficient along the binary borders of the Gibbs triangle ...
Diffusion of Quinine with Ethanol as a Co-Solvent in Supercritical CO2
(MDPI, 2020)
This study aims at contributing to quinine extraction using supercritical CO2 and ethanol as a co-solvent. The diffusion coefficients of quinine in supercritical CO2 are measured using the Taylor dispersion technique when ...
Pattern selection for convective flow in a liquid bridge subjected to remote thermal action
(AIP Publishing, 2022)
The stability of thermocapillary/buoyant flows is affected by a remote thermal source. We present a nonlinear two-phase computational study of convection in a liquid bridge that develops under the action of Marangoni and ...
Diffusion in liquid mixtures
(Springer Nature, 2023)
The understanding of transport and mixing in fluids in the presence and in the absence of external fields and reactions represents a challenging topic of strategic relevance for space exploration. Indeed, mixing and transport ...
Binary Diffusion Coefficients for Short Chain Alcohols in Supercritical Carbon Dioxide-Experimental and Predictive Correlations
(MDPI, 2023)
Experimental binary diffusion coefficients for short-chain alcohols in supercritical carbon dioxide were measured using the Taylor dispersion technique in a temperature range of 306.15 K to 331.15 K and along the 10.5 MPa ...
Behaviour of a Ternary Mixture with the Net Separation Ratio Close to Zero
(IOP Publishing, 2021)
The behaviour of the ternary hydrocarbon mixture of toluene-methanol-cyclohexane in mass proportion 0.62/0.31/0.07 is studied. The direct numerical simulation is carried out for the two-dimensional closed cavity heated ...
FTIR as a Powerful Tool for Measurements of Diffusion in Supercritical Carbon Dioxide Using Taylor Dispersion Method
(MDPI, 2022)
A new experimental high-pressure setup for measuring diffusion coefficients in supercritical fluids, based on Taylor dispersion method, and using an FTIR detector to operate up to 25.0 MPa was designed and optimized. Tracer ...
Investigation of diffusive and optical properties of vapour-air mixtures: The benefits of interferometry
(Elsevier Ltd., 2021)
While interferometry has been widely used for diffusion measurements in liquid mixtures, it was hardly applied so far to vapour-gas mixtures. The present work aims to bridge this gap. Using an improved Mach–Zehnder ...
