The Influence of Air Humidity on the Optical Properties of Aerosol Particles.
Suchánková, Lenka
2021 - anglický
Atmospheric aerosol (AA) are ubiquitous particles in the atmosphere that influence Earth’s climatic system, environmental interactions,\nand human health. AA is emitted directly from primary sources or formed in the atmosphere via the oxidation of gas-phase precursors\nwith subsequent partitioning resulting in low-volatility products into the particle phase. Among AA, great interest is dedicated to organic\naerosol (OA) since it can represent from 20 to 90% of the total submicron mass.

Removal of Contaminants from Water.
Spáčilová, Markéta
2021 - anglický
This study deals with commonly used plastics; polystyrene (PS), polytetrafluorethylene (PTFE), polyamide (PA), polyethylene glycol terephthalate (PET), polyethylene (PE), etc. Microplastic samples were prepared by abrasion from commonly available plastics to simulate real microplastic occurrence in the environment. Prepared samples were characterized by scanning electron microscopy (SEM), Raman spectroscopy and infrared spectroscopy (IR) to obtain their fingerprints. These characteristics can be applied as standards for characterization of real microplastics.

CFD Simulation of a Sub-millimetre Rising Bubble in a Stagnant Liquid.
Crha, Jakub; Basařová, P.; Kašpar, O.
2020 - anglický
Hydrodynamics of the multiphase apparatus is strongly affected by fluids used in the process. One of the main quantities, which determine the hydrodynamic behaviour is the rising velocity of gaseous bubbles. This velocity can be determined easily in small scale apparatuses, but it can be much more challenging in industrial-scale devices. For that reason, mathematical modeling is used. COMSOL Multiphysics, finite element CFD solver, was used to describe the behaviour of the single bubble rising in aqueous solutions of ethanol and n-propanol. Aqueous solutions of low-carbon alcohols are extensively used in many multiphase chemical processes such as distillation, flotation and in multiphase reactors. Bubble velocities and shapes obtained from the simulation were compared to experimental and theoretical values. Two initial diameters of bubbles were used – 0.6 and 0.8 mm. Terminal velocities and shapes deformations obtained from COMSOL of 0.6 mm bubble were in an agreement with theoretical and experimental values.
