Aspiration above wind velocity of aerosols with thin-walled nozzles facing and at right angles to the wind direction

摘要: Abstract Aspiration coefficients of sharp edged, thin-walled nozzles have been measured at 0 and 90° yaw angles in wind speeds from 77 to 309 cm/sec with aspiration velocities 2810 cm/sec, the speed being less than velocity. Aerosols homogeneous droplets di-′2-ethylhexyl sebacate, 14–32 μ diameter, were sampled a tunnel over range Stokes numbers (sampling velocity) 0.055 6.89. Deposition particles inside sampling has studied.
