Collection efficiency of particles on a ribbon in a turbulent air flow
Published in 2009
The collection efficiency of aerosol particles on a ribbon in a turbulent flow is analyzed using COMSOL Multiphysics. The flow field is solved using Chemical Engineering module and particle tracing plots are obtained using equations of motion including Khan and Richardson drag force. A MATLAB script is used to count the captured particles on the ribbon and determine the capture efficiency with varying Stokes number. The model results are compared with experimental data from literature.This type of analysis can potentially be extended to other collector geometries and can be useful for studying particle capture systems.
