Computational Fluid Dynamics (CFD) is a widely used technology. It has enabled engineers and scientists to model and predict the performance of flow in a variety of applications for decades. The limits of its applications continue to expand with the increase in computational power.

For instance, the latest trend in cloud computing has allowed small businesses and consulting firms the capability to run large complex simulations without any difficulty and hardware and software expenses. Continue reading to know HVAC CFD simulation ("In Spanish "simulacin CFD HVAC").

Ventilation (understood as air flowing within an enclosed area) is the principal method used by HVAC systems to accomplish their purpose in providing thermal comfort or any other indoor conditions.

Passive Ventilation

Also called natural ventilation, This method makes use of naturally occurring phenomena like buoyancy and wind to create pressure variations that cause a change in the air inside the structure. To achieve this special features must be included in the structure.

CFD is a powerful tool for predicting the behavior that passive ventilators have since it is precise in describing specific phenomena like buoyancy caused by variations in humidity or temperature.

Ventilation Displacement

In the conventional mixing ventilation technique, air inlets that are conditioned are set in the upper part of the space and are operated at high flow rates. The displacement ventilation technique places air intakes near the floor level and utilizes low flow rates.

The hot air created by equipment or people in the space is pushed up to ceiling levels by buoyancy and is collected and then removed from the room without the possibility of recirculation.
