Flow through randomly-oriented fibrous filters

J. Chaudhuri*, K. Boettcher, P. Ehrhard, Technical University Dortmund, Germany

Fibrous filters are often employed to remove dispersed aerosol particles from a gas stream due to low cost, high capture efficiency and low pressure drop. The performance of such a filter medium is judged based on its capture efficiency and its pressure drop characteristics. Estimating these parameters without setting up experimental investigations of each filter medium is beneficial for choosing and developing optimal filters.

In the present study, numerical simulations using ANSYS CFX are used to predict the pressure drop caused due to an air flow through a randomly oriented fibrous filter medium...
