Technologies of wind assessment
In general, it can be stated that there are 3 technologies to assess wind in the urban environment: Real life measurements Wind tunnel experiments Computer simulations (CFD or “Computational [...]
Wind assessment and guidelines for smart cities
The importance of wind assessment Cities become denser. We build more and more high-rise buildings, but these buildings typically induce high wind speeds on pedestrian level. As such, high [...]
Case study: Amstel III area in Amsterdam
Actiflow performs around 100 studies per year to advise governments, architects and developers about wind in the urban environment. An example of a wind study as performed by Actiflow, [...]
CFD: the truth and the tales
Until the end of the 20th century, CFD was typically a tool used in an academic environment, or in large aerospace companies. Back then, CFD was a very expensive and time-consuming activity. But over the past 10 to 20 years, CFD methods have developed and computational power ...
What is CFD (Computational Fluid Dynamics)?
At Actiflow, we use CFD on a daily basis to simulate gas and liquid flows. However, we feel that there is still quite some misunderstanding about this simulation method. Therefore, we provide you some explanatory information about CFD and how we use it.
