Abstract
A sampling probe was designed, fabricated, and evaluated for quantitative transport of aerosols through a conduit from a source to a sensor. The probe consists of a porous metal tube encased in a manifold through which transpiration air was passed inward to provide a moving clean air sheath that minimized particle deposition on the walls. The quantitative mass transport of aerosols and the preservation of size distribution of the transported aerosol was studied. A statistical analysis of the data conclusively demonstrates the effectiveness of the porous probe sampling concept. Tests at selected conditions show that the porous probe is effective in the preservation of size distribution. Optimization of the sample and transpiration flow ration is necessary for a given size range to obtain the most effective use of the porous probe concept.
