Wind tunnel experiments on dune sands
Earth Surface Processes and Landforms, 1981AbstractThe effect of the dry bulk density, time and the presence of roughness elements at the surface on the wind erodibility of a dry dune sand (D50 = 230–250 μm) were evaluated in a laboratory study.There is no significant correlation between the dry bulk density of the dune sand and the corresponding deflation threshold.

Wind Tunnel Experiments with Rotating Disks
2016Investigating convective heat transfer from a rotating disk subjected to streams of air requires placing a heated disk apparatus in the test section of a wind tunnel. This approach was employed for the first time by Dennis et al. [1] in 1970. Although this general experimental approach is fairly straightforward, the performance of accurate measurements

EXPERIMENTS WITH A SUPERSONIC TUBE WIND-TUNNEL
1970Abstract : An experimental study was performed of the unsteady processes in the starting period of a supersonic Ludwieg tube, a device which operates like an intermittent supersonic wind tunnel. A quick opening diaphragm located downstream of the nozzle initiates the flow. Pressure and density measurements are made in a variety of ways in Mach number 1.

An experiment research on DSP technology in wind tunnel
The 2010 International Conference on Apperceiving Computing and Intelligence Analysis Proceeding, 2010Digital Signal Processing (DS P) technologies are widely used nowadays. Aiming at the digital signals characteristic parameters in wind tunnel tests, a DS P platform based on MATLAB and C++ Builder mixed programming method is built up. The process technique and the application of the DS P platform in 2.4m transonic wind tunnel are discussed.

Wind tunnel experiments on a flapping drone
2011The motivation for this paper is to obtain a better understanding of the unsteady aerodynamic phenomena involved in flapping wing flight. The work is mainly experimental but also makes use of numerical results obtained from a vortex lattice approach. The flapping of 3D wings produces vortical structures which differ from those produced in 2D flow.

Robot-Aided Interactive Design for Wind Tunnel Experiments
2015The objective of this study is to investigate the effect of architectural geometry and materiality on airflow around buildings. For this purpose it is relevant to look for interactive design and analysis platforms that enable the analysis of architectural form and material variations while promoting the participation of designers in the analysis ...
