Planar particle image velocimetry ble gjennomført oppstrøms og i den nærliggende vaken til en roterende vindturbinmodell i laboratorieskala og aktuatordisker av samme dimensjon i en vindtunell. Den innkommende strømningen ...

We propose a novel robust 3D particle tracking technique based on a scanning laser setup. The method yields Lagrangian statistics in densely seeded turbulent flows with good spatial and temporal resolution, overcoming some ...

Volumetric tomography is a powerful tool that employs 2D projections to reconstruct unknown physical quantities in 3D fluid flows. A mathematical model of the imaging process is required to recover the desired volumetric ...

In the current study azimuthal forcing of an annular combustor with swirling flames has been performed to present for the first time the Heat Release Rate (HRR) response to all possible pressure fields of the first azimuthal ...

This paper investigates the non-linear flame dynamics of two interacting, premixed, V-shaped flames by characterising the two-dimensional topology of flame annihilation events when the separation distance, S, between them ...

Planar particle image velocimetry was conducted upstream and in the near-wake of a lab-scale free-rotating wind turbine model and compared to several actuator disks with the same dimensions. The Reynolds number of the ...

The present work introduces an annular combustion chamber operated at intermediate pressures. The combustor is operated with CH-H blends leading to a variety of azimuthal combustion instabilities. The influence of the ...

Thermoacoustic instabilities have become an increasingly relevant issue in the search for lower emissions in gas turbines, both for power production and transportation. Adoption of alternative fuels in land based gas ...

Turbulent wall-bounded flows form a cornerstone of modern fluid mechanics research and are ubiquitous in diverse natural and industrial settings. In practical scenarios, turbulent wall-bounded flows are commonly exposed ...
