A computational fluid dynamics study assessed a dedusting duct network connected to a fabric filter. The work examined how air moves through the branches, junctions and filter inlet, with attention to flow distribution, transport conditions and pressure losses.

The model provided detailed views of velocity patterns and local flow behavior at extraction points and duct connections. These findings supported a review of duct sizing, potential restrictions and the measures needed to balance extraction across the network. The study informed recommendations for vent hood improvements and refinement of the duct arrangement.
