We are pleased to announce the recent publication of a paper titled Inertial effects on fluid flow through natural media which was published in January 2026 in the journal Water Resources Research. The publication was produced as part of the NCN Opus LAP grant 2021/43/I/ST3/00228 and was prepared by a research team under the supervision of dr. hab. Maciej Matyka.

This work concerns research into the structure and flow properties of porous media at high Reynolds numbers, in the context of transport in geological rock formations and in packed structures. The authors demonstrated, among other things, that the relatively low porosity of geological samples does not at all lead to the dissipation of inertial effects in the flow – on the contrary, they can remain a key factor influencing the nature of transport.
