Measurements of dust deposition velocity in a wind-tunnel experiment [PDF]

open access: yesAtmospheric Chemistry and Physics, 2014
In this study, we present the results of a wind-tunnel experiment on dust deposition. A new method is proposed to derive dust deposition velocity from PDA (particle dynamics analysis) particle-velocity and particle-size measurements.

Scaling of wind turbine aerodynamics: wind tunnel experiments [PDF]

open access: yesMATEC Web of Conferences, 2020
A small-scale wind turbine model was designed and manufactured to study its aerodynamic thrust force and the harvested flow energy. To provide a good understanding of the aerodynamics of the small-scale wind turbine at the low Reynolds number, the performance of three different types of blade airfoils was studied.

Wind tunnel experiments: saltation is necessary for wind-packing [PDF]

open access: yesJournal of Glaciology, 2017
ABSTRACTWind-packed snow in the form of slabs or crusts is an important part of alpine and polar snow covers. Yet, the formation process of such layers is poorly understood. For example, it remains unclear whether drifting snow is necessary for wind-packing or not.
