Advances and Problems of the Nucleation Rate Measurements by the Flow Diffusion Chamber

The flow diffusion chamber (FDC) presents flow systems for measuring of the vapor-gas nucleation rate on the base of primary aerosol concentration measurements and estimation of the nucleation conditions within the axial vapor-gas flow. A particle size distribution can be measured in that experimental scheme as well. FDC decouples aerosol generation volume and aerosol detecting zones, which is useful for growing small critical clusters into optically detectable particles in residual supersaturated vapor.
