A fibrous filter has been depicted as a random array of cylinders transverse to flow direction.
Properties of the resulting aggregate of interlocking pores are evaluated. To this end a …

K= 64 X (1- e) 1, 5 [1+ 56 (1- e) 3](1) valid for fiber diameters ranging from 1.6 to 80 microns
and filter porosities ranging from 0.700 to 0.994. Davies stated that for high values of the filter …

A theoretical derivation is given of the tortuosity factor for a flow through fibrous filters, based
on purely geometrical considerations. The resulting expression for the tortuosity appears to …

A method is described for accurate prediction of the pressure drop across homogeneously
mixed multicomponent glass fiber filters. Evidence has been given of two effects, opposite in …

Based on geometrical considerations a theoretical equation has been derived relating pressure
drop to filter- and fibre-properties. Theoretical predictions are shown to be in satisfactory …

Based on geometrical considerations a theoretical equation has been derived relating
pressure drop to filter- and fibre properties of multi-component glass fibre filters. For a great …

Aerosol penetration through fibrous filters has two aspects, a fluid mechanical and a filter
geometrical one; the latter is the subject of this paper. Two effects, the structure effect and the …

In this paper a mathematical model is developed, with the aid of which the perception of
odorous pollution by the population, living in the vicinity of chemical industry, can be described …

A method is given for compact but nevertheless informative presentation of vast amounts of
air-pollution data. The percentage of time that a specified gas concentration is exceeded is …

A theoretical model is developed capable of predicting aerosol penetration through glass fibre
filters. The filter is described as an assembly of pores which conduct the flow. Some of the …
