The Flow of Mixture Vapors in the Vacuum Column K101, Nominal and Reduced Capacity
Říha, Zdeněk
2017 - English
The report contains CFD results and description of the gas mixture flow in the bottom part of the vacuum column K101. There were solved two cases. Both cases had the same geometry. The difference between ones was in quantity of vapors on the inputs. The first case was calculated for the nominal quantity of vapors. The second case was calculated for reduced quantity (60% of nominal quantity) of vapors. Calculated results of above mentioned cases are placed in report´s enclosures 1 and 2.

Cutting experiments with ASJ at 1500 bar
Zeleňák, Michal; Foldyna, Josef; Souček, Kamil; Klichová, Dagmar
2016 - English
The aim of experimental work was to determine cutting condition maximal, middle and fine traverse speeds for selected materials and thicknesses. Materials were cut at pressure 1500 bars and 10% of suspension concentration. Secondary objective is long-term monitoring of nozzles wear using X – Ray CT tomography.

Methodology of camera spectral response measurement
Melich, Radek; Václavík, Jan; Žídek, Karel
2016 - English
Spectral response of the camera will be measured using monochromator in conjunction with an integration sphere. Camera without objective will be placed in one port of the integrating sphere and light beam from monochromator will be fed into perpendicular port. Sensor of the camera sensor will be therefore uniformly illuminated by diffused light from monochromator. Proposed FWHM of the monochromator is 15 nm as a trade-off between light intensity provided by monochromator and deformation of spectral characteristic (Picture XY). Diameter of the integrating sphere has to be larger than 100 mm to ensure uniform illumination over sensor area.

Device calibration.
Melich, Radek; Václavík, Jan; Žídek, Karel
2016 - English
The device has to be calibrated in absolute terms for its brightness response. This will be facilitated by a combination of an integrating sphere and collimating objective. The emitted total light intensity will be controlled by a reference photodiode inside the integrating sphere.
