3.2.6 Wind analysis

Computational fluid dynamic allows the study of indoor, outdoor airflow pattern & comfort by evaluating the wind velocity of the site with its context. Certain aspects like wind vortex(k) allows us to see if certain quality of wind speed can be retained for longer wind comfort.

Other features include wind drag or air resistance to study the type of friction between air and the surface. Additionally, surface pressure for projects experiencing certain extreme wind velocity conditions can be used to understand if the building has any deflections. Such study is a mandate for skyscrapers.

For the purpose of this exercise wind pattern is of focus using tools provided like Autodesk Flow design and Butterfly plug in for grasshopper. Both allow live results allowing the designer explore the geometry more critically in the initial stage and make informed decisions.

Vortex(k) a whirling mass of fluid or air, especially a whirlpool wind that is characterized by rapid movement round and round.
