WebThis paper evaluates the liquid water at the gas diffusion layer-channel (GDL-channel) interface of reconstructed GDL microstructures with uniform and non-uniform fiber diameters in wave-like channels. A non-uniform GDL microstructure is reconstructed for the first time at the GDL-channel interface to evaluate droplet motion. The three-layer GDL … WebAs I understand, you want to calculate flow field inside some kind of structure, then calculate acoustic sources. It is easy in OpenFOAM to use time varying inlet velocity condition. It is also ...
