Wind Studies
Until very recently, all wind studies were made using one of two techniques:
- Sand Erosion, whereby a model of a building is placed in a wind tunnel and the degree to which sand is eroded around
the model is taken as the effective wind pattern around that model and thus the building in real life
- Smoke trail monitoring, whereby a model of a building is placed in a wind tunnel and the degree to which introduced
smoke flows around the model taken as the effective wind pattern around that model and this the building in real life.
None of these techniques is accurate, even to 20% of real wind flow.
Recent developments have changed the nature of wind modelling and now allow the
real-time computer generated streaming video of wind distribution abound a building,
taken at any section and at any elevation.
