Título Dependence of particulate sampling efficiency on inlet orientation and flow velocities
Información bibliográfica June 1982, Vol.43, No.6, p.436-443. Illus. 36 ref.
Resumen This dependence was studied with a thin-walled inlet tube at wind velocities of 250-1,000cm/s and angles for the inlet orientation relative to wind direction of 0-90°. Differences in sampling efficiency were found for particles >10µm in diameter when the aerosol was sampled 15° upward vs. 15° downward from the horizontal. For angles of 30-90° sampling efficiency was approximately a function of the Stokes number, with velocity ratio as a parameter. About half or more of the particle deposition in the inlet occurred within the first cm of the 20cm-long inlet tube.
