Anotace	Particle nucleation is one of the important phenomena encountered in both chemical engineering and environmental studies. The Laminar Co-Flow Tube (LCFT) was designed for experimental measurement of binary and ternary nucleation of mixtures of atmospheric aerosols at laboratory conditions, most often H2SO4 + H2O + amines (MEA, TEA)/terpenes (α-pinene, limonene). When nucleating components are entrained co-currently with H2S04 in the axial flow, a clearly defined nucleation zone can be formed in the axial region of the chamber. As a result, the losses of the formed particles on the device walls are minimized. Laminar flow allows mathematical modeling of velocity and partial pressure profiles in the chamber. From these, it is then possible to predict the shape and size of the nucleation zone and subsequently the nucleation rate. Two models were used for mathematical modeling of momentum and mass transfer in the LFDC. 2D axisymmetric CFD model and simplified 1D analytical model. A parametric study was carried out using both models and the influence of the individual simplifications of analytical model on overall behavior of the system was discussed.
