The effect of adsorption modeling on the stability of surfactant-laden liquid film flow
(2018)The primary instability of gravity-driven, liquid film flow is examined when the liquid contains a soluble surfactant. It is shown that the model adopted for the description of adsorption equilibrium affects significantly ... -
The effect of soluble surfactants on liquid film flow
(2012)We investigate experimentally the modifications in the dynamics of liquid film flow, resulting from the addition in water of the soluble surfactants iso-propanol (IP) and Sodium Dodecyl Sulfate (SDS). Recent experiments ... -
Investigation of various nozzles configurations with respect to IFMIF and liquid walls concepts
(2015)The study of liquid-metal free surface flows is of great interest in the fusion research, for example in the IFMIF and liquid walls concepts. In the IFMIF project, the main goal is to test candidate metallic materials in ... -
Measurements of the stabilisation of liquid film flow by the soluble surfactant sodium dodecyl sulfate (SDS)
(2016)Gravity-driven film flow of aqueous solutions of SDS is studied experimentally and the evolution of small-amplitude, regular inlet disturbances is investigated. With the addition of SDS, strong attenuation of non-linear ... -
Modeling atomic force microscopy and shell mechanical properties estimation of coated microbubbles
(2020)We present an extensive comparison with experimental data of our theoretical/numerical model for the static response of coated microbubbles (MBs) subject to compression from an atomic force microscope (afm). The mechanics ... -
Stability of liquid film flow laden with the soluble surfactant sodium dodecyl sulphate: Predictions versus experimental data
(2020)Gravity-driven liquid film flows laden with a soluble surfactant are considered, and aqueous solutions of sodium dodecyl sulphate (SDS) are taken as a case-study. Literature measurements of the critical Reynolds number for ... -
Surfactant-laden film lining an oscillating cap: Problem formulation and weakly nonlinear analysis
(2022)A surfactant-laden liquid film that lines the inside of an oscillating spherical cap is considered as a model of lung alveoli. Pulmonary surfactant solubility is described by Langmuir adsorption kinetics, modified by ...
