Digital Interferometry Applied to Thermogravitational Technique
Lapeira, Estela; Aristimuño, Patxi Xabier; Bou-Ali, M. Mounir (Springer, 2018)In this work, we have applied Optical Digital Interferometry approach to thermogravitational micro-column technique. By the new analysis, we examine the entire height of the micro-column and determine the complete concentration ... -
Effect of the supporting disks shape on nonlinear flow dynamics in a liquid bridge
Gaponenko, Yuri; Yasnou, V.; Mialdun, Aliaksandr; Nepomnyashchy, Alexander; Shevtsova, Valentina (AIP Publishing, 2021)The stability of convective flows in a non-homogeneous temperature field is affected by the shape of the container hosting the fluid. We present a nonlinear two-phase computational study of convection in a liquid bridge ... -
Investigation of diffusive and optical properties of vapour-air mixtures: The benefits of interferometry
Shevtsova, Valentina (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 ... -
Mass transport in LiBr–H2O solutions: Coupling between diffusion, thermodiffusion, and composition
Perez de Luco, Irene; Errarte, Ane; Fernandez de Arroiabe, Peru; Mialdun, Aliaksandr; Mojtabi, A.; Costeseque, P.; Shevtsova, Valentina; Bou-Ali, M. Mounir (AIP, 2025)We present an experimental investigation of mass transport phenomena in aqueous lithium bromide (LiBr–H2O) solutions, focusing on both molecular diffusion and thermodiffusion (Soret effect). Our results show a non-monotonic ... -
Measurement of optical properties of aqueous lithium bromide solutions with and without surfactant for potential use in interferometric analysis of absorption systems
Perez de Luco, Irene; Mialdun, Aliaksandr; Fernandez de Arroiabe, Peru; Errarte, Ane; Shevtsova, Valentina; Bou-Ali, M. Mounir (ACS, 2025)The refractive indices of aqueous lithium bromide (LiBr–H2O) solutions were measured over a wide range of mass fractions, from 0 to 0.62 kg/kg (62%), at seven wavelengths between 436.1 and 655 nm. Measurements were conducted ... -
A ternary mixture at the border of Soret separation stability
Prokopev, Sergei; Lyubimova, Tatyana; Mialdun, Aliaksandr; Shevtsova, Valentina (Royal Society of Chemistry, 2021)Ternary mixtures with the Soret effect are prone to triple-diffusive convection in a thermal field. The Soret coefficients of the toluene–methanol–cyclohexane mixture, measured in microgravity at a given composition ... -
The Soret coefficients of the ternary system water/ethanol/triethylene glycol and its corresponding binary mixtures
Bou-Ali, M. Mounir; Lapeira, Estela; Shevtsova, Valentina (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 ... -
