We conduct numerical studies in computational fluid dynamics (CFD) in the environmental field, with a particular focus on flue gas treatment using filtration elements such as bag filters and catalytic filters.

These studies aim to optimize the flow of flue gases and solid reactants within the line’s ducts through simulation iterations where we adjust the position of internal components such as deflectors, vanes, grids, static mixers, injection lances, and spray nozzles to ensure optimal flow uniformity while reducing pressure losses.

The injection of solids and/or droplets into the flue gas flow is simulated using a Lagrangian particle tracking “Discrete Phase Model,” which monitors particles within the continuous flow phase.

Particle tracking allows us to determine the distribution of solids in the filter cells or to eliminate any low-velocity flow zones prone to undesirable deposits in the ducts. It also enables the simulation of liquid droplet spraying and evaporation.
