[HTML][HTML] An assessment of the scalings for the streamwise evolution of turbulent quantities in wakes produced by porous objects

EH Lingkan, ORH Buxton - Renewable Energy, 2023 - Elsevier
Experimental results are presented for the evolution of three turbulent quantities in the wake
of a porous object, analogous to a wind-turbine wake. These are the mean velocity deficit …

Spatial development of planar and axisymmetric wakes of porous objects under a pressure gradient: a wind tunnel study

W van der Deijl, M Obligado, S Barre… - Wind Energy Science …, 2024 - wes.copernicus.org
We report an experimental study on the effect of a constant adverse pressure gradient on the
spatial evolution of turbulent wakes generated by different objects. A porous disk, designed …

Influence of freestream turbulence and porosity on porous disc-generated wakes

M Bourhis, ORH Buxton - arXiv preprint arXiv:2404.16975, 2024 - arxiv.org
This study aims to evaluate the effect of freestream turbulence (FST) on wakes produced by
discs with different porosity. The wakes are exposed to various freestream turbulence" …

Refined universality of the turbulence cascade

F Schmitt, A Fuchs, J Peinke, M Obligado - arXiv preprint arXiv …, 2024 - arxiv.org
Using a very large dataset of turbulent wakes, which includes different generators and
inflows, we explore the relationship between two fundamental quantities of turbulent flows …

Characteristics of wake merging downstream of side-by-side porous disks

FOJ Berstad - 2024 - ntnuopen.ntnu.no
Sammenslåingen av" wakene" til to porøse disker plassert side om side med varierende
diskavstand undersøkes eksperimentelt i en vindtunnel. To diskdesign brukes: en ikke …

Frequency adoption in porous disc wakes

TL Kolbjørnsen - 2024 - ntnuopen.ntnu.no
Frekvensadopsjon i den aksialsymmetriske vaken til porøse skiver ble undersøkt. Her
ervervet en ikke-virvelavstøtende nettskive frekvens toppen i spektrumet fra vaken til en …
