Numerical Insights on Controlled Droplet Formation in a Microfluidic Flow-Focusing Device
Somasekhara Goud Sontti, Arnab Atta
In this article, we have developed a computational model to determine the droplet formation regime and its transition in a square microfluidic flow-focusing device that eventually…
Formation characteristics of Taylor bubbles in power-law liquids flowing through a microfluidic co-flow device
Somasekhara Goud Sontti, Arnab Atta
Formation and dynamics of Taylor bubble in power-law liquids flowing through a circular co-flow microchannel are numerically investigated using coupled level set and volume-of-flui…
CFD study on Taylor bubble characteristics in Carreau-Yasuda shear thinning liquids
Somasekhara Goud Sontti, Arnab Atta
In the present study, Taylor bubble formation in two-phase gas-non-Newtonian Carreau liquid flowing through a confined co-flow microchannel is investigated. Systematic analysis are…
Enhanced accumulation of bitumen residue in a highly concentrated tailings flow by microbubbles from in-situ catalytic decomposition of hydrogen peroxide
Kaiyu Zhou, Somasekhara Goud Sontti, Joe Zhou +1
The massive volume of oil sands tailings has been one of the most challenging environmental issues. In this work, we experimentally explore a simple and effective approach to bitum…
Effects of Coal Particles on Microbubble-Enhanced Bitumen Separation in the Concentrated Slurry Flow of Oil Sands Tailings
Yiyi Huo, Mohammadhossein Golchin, Kaiyu Zhou +3
Our study investigates the segregation of bitumen residues within the transport pipeline before disposal in the presence of coal particles in carriers and microbubbles. Coal partic…
Understanding the Influence of Rheological Properties of Shear-Thinning Liquids on Segmented Flow in Microchannel using CLSVOF Based CFD Model
Somasekhara Goud Sontti, Pankaj G. Pallewar, Amritendu Bhuson Ghosh +1
In this study, two phase gas-shear-thinning liquid flow in a square microchannel is numerically investigated using the coupled level set and volume of fluid (CLSVOF) methods. A sys…
