Abstract :
[en] Numerical simulations of gas flow between two sheets of plastic MellapakTM 250 Y are performed using Lattice Boltzmann methods in laminar and turbulent regimes. Results are compared with experimental measurements and with known correlations. They are also compared with simulations using a classical CFD code. In all cases, the agreement is very good.

Commentary :
To our knowledge, it is the first time that the Lattice Boltzmann method is used in this
kind of simulations.
An original analysis of the flow profiles in the channels is presented. Numerical results
compare very well to similar simulations performed using a classical CFD code.
Simulated pressure drops between two sheets, agree fairly well with experimental data
and with the correlation of Stichlmair developed for Mellapack 250Y packings containing
many sheets.
