Opticka aparatura pro studium vzniku aerosolu.

Studying of conditions for aerosol formation has a major significance for meteorology, chemistry and power engineering. This problem is important for research of formation of rain clouds, condensation separation of multi-component mixtures or erosive and corrosive phenomena in steam systems of power plants. It is essential to predict and control both homogeneous and heterogeneous condensation for practical application plants. Although the basic theories of condensation are known, the influence of physical conditions like different admixtures is so extensive, that it is necessary to observe these influences experimentally. In the Institute of Thermomechanics a unique experimental apparatus is being built, allowing measurement of the influence of different gaseous components on the condensation of vapours of various liquids. The goal of this thesis was to develop an optical apparatus for condensed droplets detection. Developed and constructed optical set-up allows detection of condensation nucleation rates of droplets starting from J=2,105 cm-3.s-1. The objective of droplet detection is to determine the temporal courses of the mean droplet radius, number of droplets in the measured volume and the distribution of droplet radii.Available from STL Prague, CZ / NTK - National Technical LibrarySIGLECZCzech Republi
