Numerická analýza proudění v turbostrojích s vlivem vybraných geometrických prvků a proudových jevů

The non-standard behaviour of a centrifugal compressor equipped with inlet radial guide vanes during measurements on a development test bench is discussed. The problem is identified and described by means of a detailed evaluation of measurement data, dimensional analysis, mean flow calculati...

Komplexní problematika průtočné části vzduchové turbiny

The thesis deals with the problem of the flow deviation behind the rotor row of an axial turbine stage. The aim of the work is to quantitatively describe the variation of the exit flow angle from the stage in the axial gap and to determine the magnitude of ...

On 3D flow pattern behind a wall-mounted circular cylinder of finite-length

The wake behind a wall-mounted finite-length circular cylinder of the aspect ratio 2 stuck out of a wall was studied experimentally using stereo PIV technique. The cylinder was mounted normal to a ground plane and it was subjected to a cross-flow with thin boundary layer ...

Vorticity statistics in the near wake of asymmetric prismatic airfoil NACA 64-618 at negative angle of attack –10° at Reynolds numbers 1.6 ⋅ 104 and 1.6 ⋅ 105 in distance 0.0 – 0.4 × chord past trailing edge measured by Particle Image Velocimetry

The airfoil NACA 64-618 is realized by using two levels of quality: first the theoretical profile is printed on a 3D printer in a direct, “naive” way, this geometry has been scanned by using 3D scanner and based on the deviations, a better model has been processed.&#...

Turbulence topology behind different sections of the wind turbine blade

This work aimed to investigate the turbulence characteristics behind different parts of the wind turbine blade. Airfoils S807, S813, S817, and S803, which characterize the shape of the blade at different lengths, were selected for estimation. During the experiment, the chord-based Reynolds&#...
