Úprava počítačové mříže a výběr interpolačního schématu při řešení supersonického míchání proudícího prostředí
Jirásek, Vít
The injection of diluted iodine into the supersonic flow of helium was studied by means of CFD software Fluent. The computational grid was subsequently adapted, i.e. refined in the selected regions with large gradients of different defined quantities. A sensitivity of the refinement on the local and far-field solution was obtained. A sensitivity of the flowfield on the replacement of the first order interpolation scheme to the second order one in several combinations of solved equations was done. An influence of the increasing the interpolation scheme order on the far-field was found, dependent on the way of combination of the 1st and 2nd orders in selected equations interpolation.

Čenský, Miroslav ; Jirásek, Vít ; Špalek, Otomar ; Kodymová, Jarmila ; Hrubý, Jan
The paper deals with a chemical spray singlet oxygen generator for a chemical oxygen-iodine laser that was designed in the Institute of Physics AS in cooperation with the Institute of Thermomechanics AS. Preliminary experimental results obtained on parametric investigation of this device are presented.
