What is CFD simulation?

We are experts in indoor comfort modeling

Our international experience shows that numerical modelling of aerodynamics has a huge innovative potential for application in architectural and construction issues, we bring our expertise to climate engineering:

  • modeling of the microclimate of interior spaces
  • modeling of air distribution devices
  • study of indoor air quality, in relation to common pollutants and Covid risks
  • failure scenario study
  • study of comfort in extreme cases
  • Design of systems for hypercontrolled environments (clean room, cold room, data center, museum, etc.).

CFD modeling allows to explicitly reproduce the physical process of air movement in the volume of a room. Therefore, CFD modeling allows a universal approach to determine microclimate parameters for any room configuration, for all heating, ventilation and air conditioning parameters, for all seasonal influences.

Thus, CFD modeling is a virtual simulation of a room or a building. For example, certain heating, ventilation and air-conditioning parameters are defined as boundary conditions, and the distribution of controlled microclimate parameters across the room volume is analyzed. Our studies do not impose fixed boundary conditions outside the model. In this context, for example for the study of a glazing, the surface temperatures will be dependent on the various convective exchanges. In addition, it allows to approach the real conditions of temperature distribution in any point of the room.
In practice, CFD simulations are performed to confirm that the calculated indoor environment meets the requirements. If the CFD modeling shows a deviation in value from the required values, the design solutions are corrected to eliminate or limit the identified deviations. In this case, the CFD modeling is compared and repeated until satisfactory results are obtained.

Why are EOLIOS CFD simulations different?
