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...
Mixtures of anionic sodium oleate (NaOl) and nonionic ethoxylated or alkoxylated surfactants improve the selective separation magnesite particles from mineral ores during process flotation. Apart triggering hydrophobicity particles, these surfactant molecules adsorb to air-liquid interface flotation bubbles, changing interfacial properties thus affecting efficiency. The structure adsorbed layers at depends on adsorption kinetics each reformation intermolecular forces upon mixing. Up now,...
A method for the detection of bubble contours in images subcooled boiling microgravity is proposed. The refines an initial, rough contour approximation obtained from conventional background subtraction techniques. This refinement entails warping elliptical ring image region that warps this into polar image, where edge simpler. proposed exhibits robustness to a wide variety visual phenomena typically hinder contours. achieved by grouping continuous edges and their accordance with initial...
