We are pleased to announce the publication of work by Sahrish B. Naqvi, Sadia Siddiqa, Maciej Matyka, Rama S. R. Gorla, and Md. Mamun Molla, titled Enhancing Crossflow Dynamics through the Gas Injection from Multiple Cylinders. The paper has been published in the prestigious International Journal of Heat and Mass Transfer, 233, 125977 (2024), and is available at:

The work, led by dr Sahrish Batool Naqvi – Post Doc in dr hab. Maciej Matyka’s group from the Institute of Theoretical Physics, concerns the phenomena of gas dispersion in the flow of a fluid through a system of cylinders immersed in a fluid.

The paper relates to fundamental research into the nature of flow and the phenomenon of fluids mixing with each other, is the result of many months of calculations and solutions of the Navier-Stokes equations performed by Naqvi using OpenFOAM software.

The work is done under the INERTFLOW grant, “Inertial Effects in Fluid Flow in Complex Porous Media” (NCN 2021/43/I/ST3/00228) carried out from 2022 to 2026.

The figures show selected simulation results of the dispersion phenomenon under study presented as constant speed contours (the brighter the color, the higher the absolute value of the speed). The figure shows how dynamic and nonlinear phenomenon (vortices and their transport) we are dealing with.
