Parametric Study of the Device Angle Dependency of a Single Vortex Generator on a Flat Plate
(2014-01-23)
[EN] A detailed study of the device angle dependency of a single vortex generator (VG) is presented in this paper. A single Vortex Generator on a test section wall case, with four different positions of the device angle ...
Self-Similarity and helical symmetry in vortex generator flow simulations
(IOP Publishing, 2014)
According to experimental observations, the vortices generated by vortex generators have previously been observed to be self-similar for both the axial (u(z)) and azimuthal (u(circle minus)) velocity profiles. Further, the ...
Cell-Set Modelling for a Microtab Implementation on a DU91W(2)250 Airfoil
(MDPI, 2020-12-20)
Microtabs (MTs) are a regularly used flow control device in terms of wind turbine optimization. The present study introduces the application of the novel cell-set model for an MT implementation on a DU91W(2)250 airfoil. ...
Experimental Air Impingement Crossflow Comparison and Theoretical Application to Photovoltaic Efficiency Improvement
(MDPI, 2020-07-10)
The photovoltaic cell temperature is a key factor in solar energy harvesting. Solar radiation raises temperature on the cell, lowering its peak efficiency. Air jet impingement is a high heat transfer rate system and has ...
