Experimental measurements of rolling stock aerodynamics

Bulletin of Siberian State University of Transport, 2022
The increase in the speed of trains on railways is accompanied by a significant increase in the aerodynamic impact on structures located in close proximity to the axis of the track. This factor is of particular importance in the development of high-speed rail lines (HSR).

The Experimental Approach in Aerodynamic Design

2020
Aerodynamics is the study of the flow of air around bodies, generally an aerial or ground vehicle, but also structures, turbomachine blades and rotors, wind turbines, or in more diverse cases such as bikes and other sports equipments.

Theoretical and experimental aerodynamics of the sailwing

Journal of Aircraft, 1971
The sailwing is a unique type of semiflexible foldable wing. A brief description of its construction, basic properties, and some past research, is used to introduce an analytical and experimental study of its aerodynamic characteristics. Emphasis is placed on an approximate structural analysis which treats the nonlinear behavior of the sail deflection.

Experimental evaluation on vehicle aerodynamic noise performance

International Journal of Vehicle Performance, 2018
In this study, a passenger car was tested for its aerodynamic noise performance in terms of sound pressure level in the wind tunnel at Tongji University (Shanghai Automotive Wind Tunnel Center), where the phase microphone array was used along with sound surface microphones and artificial heads combining with the adhesive tape sealing method.

Experimental investigation of ionospheric aerodynamics effects

AIP Conference Proceedings, 2019
The accurate prediction of the motion of resident space objects (RSOs) in Low Earth Orbit (LEO) requires knowledge of all forces acting on these objects, which includes active and inactive (e.g. debris) objects. In this context, charged particle interactions with RSOs and associated orbital perturbations resulting from charged aerodynamic effects, i.e.

An experimental study of highway aerodynamic interferences

Journal of Wind Engineering and Industrial Aerodynamics, 1984
Abstract Energy and material considerations today point in the direction of smaller and lighter vehicles. With further reductions in the weight of vehicles, aerodynamic forces emerge as a major factor in energy and stability calculations. In the present study the aerodynamic interference forces between two vehicles (passenger cars and articulated ...

Experimental study of the aerodynamics of a larynx model

The Journal of the Acoustical Society of America, 1992
The aerodynamic characteristics of the source of voicing during phonation were investigated using a larynx model. An experimental setup consisting of a uniform cylindrical tube partitioned by a flexible wall with an opening, which was made geometrically similar to the human glottis, was built.

Experimental Investigation of Annular Wing Aerodynamics

Journal of Aircraft, 2009
A low-speed wind-tunnel investigation was conducted to explore the behavior of annular (ring) wings. Effects of aspect ratio as well as gap were investigated. Ring wings using a low Reynolds number Eppler section and a NACA 0012 profile were manufactured and tested. Measurements were recorded using a six-component sting balance.

Aerodynamics and ventilation in buildings: Experimental investigation

Solar & Wind Technology, 1987
Abstract Application of the present building codes in Saudi Arabia results in groups of narrowly spaced rectangular shaped buildings with internal lightwells, as a source of natural ventilation for service spaces. Experimental work is conducted on a scale model to investigate the natural ventilation conditions in and around such buildings.
