Abstract:

The process of aspiration of aerosol particles in the atmosphere is considered for the case, when typical linear scale of turbulence is much larger than typical diameter of a sampler inlet. Estimations of the efficiency of aspiration of aerosol particles in the turbulent atmosphere have been made for the surface atmospheric layer using known empirical equations for the laminar flows. We used the method of modeling the series of the instant values of wind velocity pulsation and pulsation of concentration with a preset distribution laws and correlation in calculations. It is shown that the corrections for the atmospheric turbulence are, as a rule, insignificant. Only in some cases, usually with high permissible Stokes numbers and intensity of concentration pulsation, they can reach 20%.
