The more complex a room is (large volume and height of the room, uneven arrangement of heat sources, high concentration of people, large glass surfaces, etc.), the less effective standard engineering techniques will prove to be in organizing an optimal air distribution scheme for space mixing.
Consequently, it results in cold draughts in the workplace, the spread ofodors in restaurants, obvious discomfort in shopping and entertainment complexes, the appearance of condensation on pool and atrium walls, overheating of the upper floors of the atriums in summer, or significantly different temperatures in different parts of the auditorium due to the influence of air conditioning systems, etc.
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:
CFD modeling allows to reproduce explicitly and precisely the physical process of air movement in the volume of a room. Therefore, CFD modeling allows a universal approach to determining 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, some parameters of heating, ventilation and air conditioning are defined as boundary conditions, and the distribution of the controlled parameters of the microclimate in the volume of the room is analyzed.
Our studies do not impose any fixed limit 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, this makes it possible to approach the real conditions of temperature distribution at any point in the room.
In practice, CFD simulations are performed in order to confirm that the calculated indoor environment meets the requirements. If the CFD modeling shows a value deviation 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.
