Abstract

Numerical simulations were performed to investigate convection, diffusion and thermophoretic transport of aerosol particles inside a particulate probe used for intrusive sampling of jet engine exhaust gases. Particulate losses occurring inside the probe due to diffusion and thermophoresis were quantified. The model was tested against results from previous theoretical and experimental investigations and was found to be reasonably accurate.
