I'm a structural engineer and I need to understand the additional forces that wake turbulence may cause on a building near a runway.
I can determine the natural wind speed and associated forces on the building, but I need to calculate the additional wind forces/ turbulence (or airflow velocities) caused by aircraft operating on a nearby runway.
The runway is 3,400m (11000 ft) long, and the position of the building is 800 meters along the extended runway centreline and 300 meters to the side of it. These measurements are from the very end of the paved surface (which I will have to assume to be the first/ last possible contact point from the aircraft for the design of the building). The runway is approached by (and departed from) that end.
How do I calculate the airflow velocities at ground level below an aircraft (assume an Airbus A380) at the building's location? The surrounding ground is flat and level.
