title: Nozzle sampling bias.
abstract: A mathematical model is proposed to describe the sampling bias in anisokinetic sampling of aerosols. The nozzle sampling bias is described as a function of the particle's free stream inertial parameter, P, and the particle's free stream Reynolds number, Re0, and the suction ratio, w0, of the sampling nozzle. Tables of experimental values for these parameters were developed from Badzioch's experimental data, and the proposed mathematical model was developed via trial and error fitting of the results to many possible mathematical models.
