Et estimat av effekten fra fly-genererte virvler på bebyggelse i nærheten av Kjevik flyplass

On some occasions, gusty winds caused by aircrafts during approach to Kjevik airport have caused tiles to fall down from roofs, causing potential damage. In the current study, initiated by the Norwegian air traffic and airport management, the evolution of air-craft generated vortices, as they hit simple buildings and/or the ground is simulated using the numerical package CLAWPACK. The simulations show that even for B-737 generated vortices, only modest wind-speeds (up to 10 niis) wil] occur close to buildings, expected to cause in worst cases only minor if at all any damage.
