Science - Meteorology | | English term or phrase: wind tunnel/tunneling | Bonjour,
connaissez-vous l'effet de "wind tunnel" en météorologie et savez-vous comment traduire ce concept en français ?
"The platform crashes with enough force to twist and bend its aluminum frame. It swings through the air like a giant pendulum driven by what atmospheric scientists call a “wind tunnel” effect."
"Wind tunneling occurs when a city’s buildings act like barriers. As strong gusts squeeze between buildings, the wind actually accelerates around and through the tight passages, creating violent and unpredictable updrafts." |

| | French translation:effet venturi | Explanation:
En fait, on en parle pour le vent et aussi pour les fluides. Dès qu'un goulet d'étranglement se forme du fait d'un obstacle, cela provoque une accélération du fluide ou de l'air entre les parois. |

DEF – A speed-up effect created by wind pressure in a natural corridor which allows a wind turbine to harness wind kinetic energy stronger than in the surrounding area. Source, fiche 1, Défintion 1 - tunnel effect
CONT – Speed up effects: Tunnel effect. If you push an ordinary bicycle air pump, ... you will notice that the air leaving the nozzle moves much faster than the speed with which you are pushing. The reason, of course, is that the nozzle is much narrower than the cylinder in the pump. If you take a walk between tall buildings, or in a narrow mountain pass, you will notice that the same effect is working: The air becomes compressed on the windy side of the buildings or mountains, and its speed increases considerably between the obstacles to the wind. This is known as a "tunnel effect". So, even if the general wind speed in open terrain may be, say, 6 metres per second, it can easily reach 9 metres per second in a natural "tunnel." Placing a wind turbine in such a tunnel is one clever way of obtaining higher wind speeds than in the surrounding areas. Source, fiche 1, Contexte 1 - tunnel effect
DEF – [...] effet accélérateur engendré par la compression du vent dans un couloir naturel et qui permet à l'éolienne qui y est installée de capter une énergie cinétique du vent supérieure à celle de la z
