Investigation of Transonic Flow through Linear Cascade with Single Blade Incidence Angle Offset
Fürst, J. ; Musil, Josef ; Šimurda, David
The contribution deals with numerical and experimental investigation of the effect of incidence angle offset in a two-dimensional section of a flat linear blade cascade in a high-speed wind tunnel. The aim of the work is to complement ongoing research of quasi-stationary approximation of aerodynamic flutter by examination of setups leading to transonic flow regimes. The numerical simulations were realized by finite-volume, in-house code developed on top of the open-source software package OpenFOAM. The experiments were conducted in correspondence with the setting of numerical simulations. The comparison of experimental and numerical data is presented on the isentropic Mach number distributions at various locations in the blade cascade. The description of transonic flow structures in the vicinity of blades is also provided.
Measurement on Compressor Cascade KOBRA
Luxa, Martin ; Šimurda, David
The report contains results and evaluation of conducted optical (shadowgraph and schlieren technique) and pneumatic measurements on the profile cascade intended for the tip section of the first rotor row compressor blade.
Design of compressor cascade KOBRA
Fiala, Petr ; Luxa, Martin ; Šimurda, David
Prismatic profile cascade has static pressure taps on suction and pressure side of profiles, which form the interblade channel in the middle of the cascade. The sidewalls of the cascade are equipped with slots for boundary layer control.
