This repository is an educational project focused on gas flow through porous media. Its main goal is to explain and implement engineering models for pressure drop in porous materials, with particular attention to Darcy–Forchheimer behavior, compressibility effects, and the differences between flat and cylindrical porous geometries. The bubbler is mentioned only as the original motivation for the study, while the core content is the physics and numerical modeling of porous flow. Two reports (PDF) are attached in English and Russian.

The project combines theory and computation. It derives practical pressure-drop relations for porous samples, discusses the role of permeability, porosity, pore size, and inertial effects, and extends the analysis to compressible gas flow. In addition to the analytical part, the repository includes Python tools for numerical evaluation of pressure drop under different assumptions and measurement schemes.

This work is intended for learning, exploration, and preliminary engineering studies. It may be useful for students, researchers, and engineers interested in porous materials, gas transport, filtration-like structures, spargers, or related laboratory systems. It is not presented as a validated industrial design package, but rather as a transparent educational framework that connects physical reasoning, mathematical derivations, and numerical implementation.
