Abstract:
This paper details the use of commercially available Computational Fluid Dynamics (CFD) codes, grounded in Navier-Stokes theory and the Langevin particle equation of motion, to simulate filtration processes. The primary objective is to compute the particle capture efficiency and pressure drop across selected two- and three-dimensional fiber arrays. The methodology involves first calculating the air velocity vector field within the fiber matrix, followed by superimposing the Langevin equation to model particle capture, thereby combining Brownian motion, inertia, and interception mechanisms into a unified approach.
