Abstract

In this study, a numerical computational model for prediction of fluid flow and aerosol particle transport in a long column electrical mobility spectrometer (EMS) has been developed. The internal three-dimensional (3D) structure of an EMS (Intra and Tippayawong, Korean J., Chem. Eng., 26(1), 269 (2009)) was employed to simulate the complex flow pattern and aerosol particle trajectories in the EMS, including the swirling flow that develops near the sheath air inlet slit. The incompressible Navier-Stokes equation is numerically calculated for the gas flow and particle trajectories, with a commercial computational fluid dynamics (CFD) software package, FLUENT 6.3, using a finite volume method. The calculated results agreed with the previous published results in the literature. Prediction of fluid flow and aerosol particle transport were also particularly useful in the EMS design.
