“…This result suggests that the decrease in material resistance, due to an increase in the spread area of the thin PTFE membrane with the increase of its pleat height, dominated the decrease in the overall filtration resistance, regardless of the higher structural resistance as a result of potentially closer pleat peak at the larger pleat height. The closer pleat peak could make it more difficult for the air to pass through the filter, thereby causing higher structural resistance . However, the resistances of the pleat H12 filter were comparable between the different pleat heights (Figure b).…”

“…During dust loading, the pleated structure of the filter affects the trajectory of the particles [ 3 , 18 , 19 , 21 , 28 30 ] and leads to the uneven deposition of dust particles [ 6 , 11 , 31 ]. Some scholars found that the dust deposition on the pleated filter media is closely related to the Stokes number ( S tk ), which can be expressed as Eq (1) [ 18 , 30 ].…”

“…The pleating of the filter media can lead to the change of flow field [ 7 10 ], resulting in the uneven deposition of dust particles which in turn affects the evolution of the pressure drop [ 11 13 ]. Therefore, the flow field of the pleated filters and the uneven deposition of dust particles are to be investigated.…”

“…Li et al 8 studied the effect of pleat geometry on small-scale pleats experimentally and concluded that the pleat ratio should be below 1.59 to achieve a good filtration effect and the influence of the pleat ratio is more pronounced on the pressure differential as the superficial velocity increases. Teng et al 9 found that the effective filtration area increases with a pleat ratio of 2.22–3.70. A larger pleat ratio could allow the larger dust particles to deposit at the pleat corners more easily.…”
