Abstract

Porous materials are usually applied in HVAC system ducts as passive silencers.  The introduction of silencer materials such as baffles in the duct stream produces pressure drop to the fan system.  The pressure drop measured in pascals becomes significant in elbow silencers where 90 degree turns are the norm.  The pressure drop of elbow silencer systems were evaluated using a CFD method as well as simple ASHRAE procedures.  The comparison of the two methods is presented in this paper.
