✦ Synopsis

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 be a function of filter and fibre properties. For laminar air flow the tortuosity factor is calculated as a function of porosity and of filter composition. Although the resulting curves are in quantitative agreement with the experimental work of Sullivan, frequently referred to, there is much evidence

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 Monte Carlo technique is applied to generate an isotropic random line array; it could he proved that properties der

## Abstract Liquid aerosols produced in many manufacturing and refining processes need to be filtered from the exhaust streams. Where wettable fibers are used in the filters, the aerosol liquid collects on the fibers. Observation shows that thin films develop on the fibers, and the liquid drains do

Chemical, manufacturing and refining processes often generate toxic liquid by products that are emitted as liquid aerosols in the waste stream. Wettable and nonwettable fibers can be used to filter these exhaust streams. The behavior of liquid aerosols and droplets on nonwettable fibers is studied b

The inertial interception mechanism of particle-fiber collision in fibrous filters is described. The main mechanisms by which particles are retained in filters together with the effect of a number of operating parameters are discussed. The effect of particle size, gas velocity, relative humidity, a
