Paper Title:
Numerical Simulation and Analysis of Velocity Field in Folding-Type Air Filters
  Abstract

In this paper we contrast the velocity fields of uniform and non-uniform porous filter media in folding-type air filters under different porosity conditions by numerical simulation. In addition, the non-uniformity of those velocity fields are measured and calculated. The results show that the non-uniformity of air flow velocity is related to pressure drop, and regarding the media whose porosity is above 95% (Δ>95%), an effective way to improve the velocity uniformity and reduce the pressure drop is to increase the porosity of filter media and make the media capture particles evenly.
