The effect of the volume fraction of the fibers in fibrous air filters on the collection efficiency of a single fiber has been examined both theoretically and experimentally in the inertia predominant region. Numerical solutions have been obtained for the flow around a circular cylinder in a cell determined by the volume fraction of the fibers for a Reynolds number of 10 and the potential flow. Particle trajectories have been calculated in the cell by introducing the above numerical values into the equations of particle motion. As a result, the inertia-interception efficiency was evaluated through four parameters; inertia parameter, interception parameter, Reynolds number and volume fraction. Experimental data on model filters, which are made of a uniform parallel arrangement of wires orientated at right angles to the flow direction have shown good agreement with the calculation results in the intermediate Reynolds numbers region.
