Precision resonance energy scans with the PANDA experiment at FAIR: Sensitivity study for width and line shape measurements of the X(3872)

This paper summarises a comprehensive Monte Carlo simulation study for precision resonance energy scan measurements. Apart from the proof of principle for natural width and line shape measurements of very narrow resonances with PANDA, the achievable sensitivities are quantified for the concr...

An experimental study of turbulent mixing in channel flow past a grid

Grid turbulence is considered to be a canonical case of turbulent flow. In the presented paper, the flow structure is analyzed from the point of view of mixing properties, where vortical structures and their properties play a significant role. That is why the effect of va...

Structure turbulent flow behind a square cylinder with an angle of incidence

This article shows the results of a study of the structure of turbulent flow behind a square profile ALUTEC 45×45mm with T-slots. The angle of rotation of the profile relative to its axis varied α=0°, 15°, 30° and 45°. During the experiment, the flow velocity was 5m⋅...

Experimentální vzduchová turbína VT-400.

The nuclear power plant also includes a secondary cycle. One of the main components of the cycle is a steam turbine. The flow through the flow path is very complicated and significantly affects the turbine efficiency. An single-stage axial experimental air turbine is located i...

The Solution of the Stationary Aeroelasticity Problem for a Separation Channel with Deformable Sinusoidal Walls

One of the most urgent problems concerning the design of inertial separation devices is the failure of the trapped liquid film from the contact surfaces due to the contact with the turbulent gas-liquid flow. For extension of the range of the effective inertial separation, a&#x...

On the streamwise structures in the boundary layer under adverse pressure gradient on an inclined plate

The presented study is focused on experimental investigation of a boundary layer on a flat plate in adverse pressure gradient. The flat plate is placed in a regular flow, the pressure gradient is generated by the plate inclination. The preceding studies deal with structure of&...

Experimental Research and Numerical Analysis of Flow Phenomena in Discharge Object with Siphon

This article presents results of the experimental research and numerical simulations of the flow in a pumping system’s discharge object with the welded siphon. The laboratory simplified model was used in the study. Two stationary flow regimes characterized by di erent volume flow r...

Experimental and numerical study of controlled flutter testing in a linear turbine blade cascade

In this paper, experimental testing of flutter and numerical simulations using a commercial code ANSYS CFX and an in-house code TRAF are performed on an oscillating linear cascade of turbine blades installed in a subsonic test rig. Bending and torsional motions of the blades a...

A shape modification of the balancing slot of the impulse turbine stage with the drum rotor arrangement

At the previous conference in Český Krumlov it was presented how the balancing slots may influence the efficiency of the impulse turbine stage with the drum rotor arrangement. A few options for shape modification of the balancing slot were also suggested. Implementation of the ...
