Modeling Particle Deposition in Ventilation Ducts

  title={Modeling Particle Deposition in Ventilation Ducts},
  author={M. Sippola and WW Nazaroff},
This paper describes predictions from two models of fractional particle loss in four typical HVAC duct runs. One model is a state-of-the-art Eulerian formulation; the second is based on empirical fits to experimental particle deposition data collected in a laboratory. The experiments are briefly described and sample results are presented. The Eulerian model only predicts deposition from fully developed turbulence, while the empirical model can be applied to duct bends and developing turbulence… CONTINUE READING
