Novel Approach In Binary Nucleation Experiments Performed Under Laboratory Conditions

Popis výsledku v původním jazyce

In this work we introduce a novel device especially designed for binary or ternary nucleation experiments - a laminar co-flow tube (LCFT). The first experiments performed on this type of device were focused on binary nucleation of sulfuric acid-water. Main advantage of the co-flow design of LCFT is, that the turbulent mixing zone is not present. Simple modeling of laminar flow then leads to more accurate determination of location and composition of nucleation zone. The sheath flow of water vapor surrounding the axial sulfuric acid stream prevents the losses of H2SO4 on the chamber wall. A detailed description of the whole experimental device and validation of operational set-up parameters can be found here (Krejčí 2010). At this device, concentrations of newly formed nuclei versus time are measured as an input parameter for mathematical model.
