	Comparison of Transonic Flows Through Two Tip-Section Turbine Blade Cascades with Different Flat Profiles Musil, Josef ; Příhoda, Jaromír ; Fürst, J. ; Luxa, Martin ; Šimurda, David The contribution deals with numerical simulations of 2D compressible flow through two variants of the tip-section turbine blade cascade with a flat profile for the subsonic inlet. Simulations were realised by means of the OpenFOAM code using the γ-Reθ bypass transition model completed by the two-equation SST turbulence model. Predictions were focused particularly on the impact of the shock-wave/boundary-layer interaction on the flow structure in the inter-blade channel. Beside the effect of the inlet angle on the flow around the leading edge was studied. Numerical results were compared with optical and pressure experimental data. Detailed record
	Numerical simulation of dynamic loading of a test blade in forced torsional vibration Šidlof, P. ; Vomáčko, V. ; Lepičovský, Jan ; Šimurda, David ; Štěpán, M. ; Luxa, Martin Within a new project focused on blade flutter research, building on previous experience with the NASA Transonic Flutter Cascade facility, static blade cascade and airfoil flutter experiments realized in cooperation between the Institute of Thermomechanics and Technical University of Liberec, a new test facility is under development for the investigation of high subsonic and transonic flow in a blade cascade under forced torsional oscillation. Apart from aerodynamic loading of the blades, the oscillating blade will be exposed to significant structural stresses due to the highfrequency torsional vibration. In order to avoid structural integrity issues from high-cycle fatigue, a numerical simulation of the stress and displacement of the blade was realized. Regions where equivalent stress reaches maximum values were identified, and elastic deformations were computed. The limits in oscillation amplitude and frequency for the safe operation of the experimental setup were discussed. Detailed record

	Numerical and Experimental Investigation of Compressible Viscous Fluid Flow in Minichannels Prausová, H. ; Bublík, O. ; Vimmr, J. ; Hála, Jindřich ; Luxa, Martin The study is focused on the value of critical Reynolds number Rec and also on suitable approaches to the measuring and modelling of the compressible viscous fluid flow in narrow channels. The results of numerical simulations performed using an in-house code based on the discontinuous Galerkin finite element method are compared with experimental data. The chosen approaches and numerical methods prove themselves to be suitable for investigation of the compressible flow in narrow channels and can be used in future research in this area.

	Effects and development of the near-wall flow in the hub section of the last stage steam turbine blade Hála, Jindřich ; Šimurda, David ; Luxa, Martin ; Fürst, J. ; Bobčík, M. ; Novák, O. ; Synáč, J. This paper deals with the investigation of three-dimensional vortex structures in the near-wall region of the blade cascade which represents the model of the hub section blading of last stage blades of a steam turbine. The investigation aims to describe the development and mutual interaction of the vortex structures and its influence on the kinetic energy losses. The analyses are based on the RANS numerical simulations and experiments conducted in the high-speed wind tunnel.\n\n Detailed record
