Effect of Pleat Angle on Pressure Drop in H14 HEPA Filters: A Mathematical Analysis with Corrections for Real Filter Behaviour

The influence of pleat angle on the pressure drop of H14 HEPA filters was investigated through a mathematical model that represents the filter as a system of converging–diverging channels coupled with porous filtration media. The analysis was conducted for pleat angles ranging fr...
