Abstract
When using a new filter, dust particles first settle on the
fibers of the filter. As contamination increases, the thickness of
this dust layer increases and causes a decrease in the pore volume.
This leads to the increase in pressure difference. This increase in
pressure difference is a typical phenomenon in depth filtration.
The pressure difference rapidly increases when the pore volume gets
exhausted. When it reaches a specified value by the manufacturer,
the filter should be replaced. While studying this process it is
found that there is a new parameter that affects the performance of
engine pleated air filter, which is the efficiency of the effective
filtration area.
The efficiency of the effective filtration area
(ηeff) is defined as the ratio
between the effective filtration area and the total geometric
filtration area. The effective filtration area is found to decrease
with the increase in temperature, specific dust and flow rate.
