Flow structure in the mixing chamber of an experimental model of a supersonic jet
Dvořák, V. ; Šafařík, Pavel
The experimental data of supesonic flow past the model ejector are preseted and analysed.
Local detection of turbulent signals using instantaneous spectra
Uruba, Václav
The method of turbulent - nonturbulent decision for an anemometric signal have been sugested using the instantaneous spectra. The wavelet transform has been applied.
Calculation of the physical properties of some gases mixtures
Mazur, Oton ; Jonáš, Pavel ; Šarboch, Jaroslav ; Uruba, Václav
Formulas for calculation of the physical properties of some couples of gases are presented, which are necessary for the measurement of concentration and flow velocity by means of thermoanemometer.
Sensitivity of a probe with two heated sensors to concentration of a helium admixture
Jonáš, Pavel ; Mazur, Oton ; Šarboch, Jaroslav ; Uruba, Václav
Formulas of the dependence of the CTA output signals to the change of concentration of the Helium admixture into air flow are derived. They are analysed usingan example of a particular dual sensors probe.
Modelling of flow separation in a curved channel with the squared cross-section
Příhoda, Jaromír ; Sedlář, M.
Turbulent flow in a curved channel of the squared cross-section was numerically simulated using the CFX-TASCflow software. The detailed analysis of secondary flow and flow parameters in the bend region was carried out.
Numerical solution of some 2D incompressible flow using dynamical effects
Honzátko, R. ; Horáček, Jaromír ; Kozel, K.
The work deals with a numerical solution of 2D inviscid incompressible flow throuht a cascade and over a profile in a channel. The finite volume method in a form of cell-centered scheme at triangular and qudrilateral mesh is used. the composite scheme applied to a numerical solution consists of more dissipative part adn less dissipative par. Governign system of equations is the system of Euler equations.
