Opis:
In this paper, the specified issues that occurs in the numerical modeling of complex phenomena of chemical reactions intensified with forced fluid flow in the thermocatalytic reactor channels on the intermetallic phase of Ni3Al are presented. Based on the example of flowing mixture containing helium contaminated by methanol in a horizontal microchannels, heated from the outside, received results of the experiment were shown and compared with computational fluid dynamize calculations. However, standard version of commercial code have been expanded by user definedfunctions. These extensionstransformed the calculation mechanisms and algorithms of computational fluid dynamize codes adapting them for the micro-flow cases and increased chemical reactions rate on an interphase between fluid and solid. Results obtained on the way of numerical calculations were compared with experimental data receiving satisfactory compliance.

Opis:
Organosilicon compounds are of great significance in modem world and may be found in various branches of chemistry and our daily life. The silsesquioxanes are their specific derivatives. Their uniqueness results from the presence of inorganic siloxane Si-O-Si core and tunable functional organic coronae which classifies them as hybrid systems. These compounds attract great attention due to their exclusive properties derived from chemically and thermally robust organic- inorganic framework, e.g. thermal stability, high oxidation resistance, good mechanical and optical characteristics, and other features. This fact, along with the elaboration of synthetic routes for their functionalization, affects the broad area of their application. Many research laboratories are focused on development of selective and effective synthetic procedures for obtaining of the abovementioned compounds. In recent years, the number of reports on the synthesis of hybrid materials with variety of applications has been growing rapidly, however, it still meets unknown perspectives.
