This publication lays the foundation for description of Multiscale Boiling Experiment, which was conducted within two measurement campaigns on International Space Station between 2019 and 2021. The experiment addresses fundamental questions about two-phase heat transfer during boiling processes. For this purpose, single or few subsequential bubbles are selectively ignited a heated substrate using short laser pulse. A detailed investigation phenomena is possible, as process temporally slowed...
The spreading of the water droplets falling on surfaces with a contact angle from 0 to 160° was investigated in this work. Superhydrophilicity surface is achieved by laser treatment, and hydrophobization then applying fluoropolymer coating different thicknesses. chosen approach makes it possible obtain wettability, but same morphology. parameter t* corresponding time when capillary wave reaches droplet apex established. It shown that for earlier moments, height change does not depend type...
The research focuses on optimizing the production of hydrogel microspheres using droplet microfluidics for pharmaceutical and bioengineering applications. A semiempirical method has been developed to predict dynamic interfacial tension at interface ion-cross-linked sodium alginate microsphere-sunflower oil modified with glacial acetic acid Tween 80 surfactant. These are produced in a small-scale coaxial device that is manufactured affordable DLP/LCD 3D printing technology transparent...
Two-phase flows of distilled deionized nanofiltered water and nitrogen gas in a microchannel with height 50 µm width 20 mm have been investigated experimentally, which the schlieren method was used to determine main features two-phase flow microchannel. The regimes boundaries between them were investigated, following distinguished: bubble, churn, jet, stratified, annular. optical methods allow detecting liquid film on lower upper walls peculiarities discovered almost all regimes, such as...
A numerical and experimental study of Taylor bubbles in a square minichannel with side 1 mm has been carried out. three-dimensional simulation was performed using the volume fluid method open source package OpenFOAM. An high-speed shadow automatic processing. The characteristic flow regimes are investigated, main attention being paid to regime. In course work, calculated data were compared, their good agreement shown. distribution velocities liquid gas, as well film thickness bubble, is...
Laser-induced fluorescence and Schlieren techniques have been used for study of gas−liquid flow inside the channels with heights 0.1 0.2 mm. The two-phase regimes transition between them are studied. classical in channel (bubble, stratified, churn, annular) were detected. New gas jet-drop regime was identified short horizontal rectangular channels. Experimental information allows us to define characteristics churn determine precisely boundaries flows. It shown, that height decreasing, area...
Abstract A mathematical model of the liquid-vapor interface based on Onsager reciprocity relations and kinetic theory gases is proposed. In framework this model, heat mass fluxes through an are related to pressure temperature jumps across it. The developed applied wedge-type geometry simulate near-contact-line behaviors, where effects paramount importance in view flux singularities. results implementation case FC-72 evaporation shown comparison a very widely used Schrage-type relation.
