Near-exit coalescence – a so far unknown limit to microbubble smallness
Tesař, Václav ; Šonský, Jiří
Gas bubbles in a liquid are required in applications to be of the smallest possible bubble size. Authors studied microbubble formation using a high-speed camera and discovered that bubbles increase their volume near the aerator exits by mutual coalescence. This effect presents a limit to how small microbubbles can be produced. The discovered conjunction effects are very fast and this is probably the reason why they have so far escaped attention.
Microfluidics in search for catalysts for biomass conversion into liquid fuels
Tesař, Václav
Paper surveys recent developments of combinatorial chemistry characterised by testing many substances and their mixtures simultaneously. Attention focuses on the progress made possible by applying small-scale no-moving-parts fluidics. Encountered problems like small Re and their solutions are demonstrated on author's development of a microfluidic unit for parallel testing of catalysts improving effectiveness of Fischer-Tropsch synthesis of liquid fuels from biomass.
