Particle penetration through CAM-sampler aerosol transport lines
A numerical model is developed to predict particle deposition in aerosol sampling lines due to turbulent diffusion and gravitational settling. Input parameters to the model are particle diameter, air flow rate, tube length, and the inside tube diameter--the latter will be referred to as tube diameter for brevity. The flow rate of air in the sampling lines at WIPP site is in the range of 1--2.5 cfm. Additionally, models developed by others are set up for determining for penetration of aerosol through tube bends and the aspiration of air into the transport tubes. In general, the results of the calculations show aerosol transmission to the CAM samplers to be most significantly impacted by inlet operational characteristics and by the presence of horizontal tube runs and tube bends. 6 refs., 30 figs., 3 tabs.
