CFD (Computational Fluid Dynamic) modelling is used to simulate the movement and flow of gases and liquids and associated heat and mass transfer process. In the built environment we often need to understand air movement and its effects on temperature distributions and dispersion/mixing of gasses, smoke and other pollutants.
Incorporating CFD simulation as part of the design process offers reassurance as it allows a complex design to be tested as a computer model before any construction cost is incurred. Design certainty can be established as scenarios can be accurately simulated with the calculated results graphical displayed providing an “easy to relate to” representation.
The cost-effective simulations answer all the “Where, What, When, How” questions providing the design confidence. For example:-
Where will the fumes disperse once discharged to atmosphere? Extracted fumes can be simulated enabling the correct siting of discharge stacks ensuring adjacent properties will not be affected and dispersed fumes do not get brought back into a building via windows or HVAC equipment.
What if a fire broke out the atrium? With CFD the fire and smoke movement can be simulated to assist with escape planning and smoke clearance system design.
What are the detailed temperature distributions and will this effect comfort of the occupants or operation of equipment? CFD simulation can simulate internal spaces in buildings and provide a detailed understanding of the distribution of airflows, temperature and solar radiation.
Is the ventilation system adequate and will it provide acceptable operating conditions? In industrial buildings CFD can be used to assess removal of heat or fumes and indicate whether the design criteria are met. It can be used to optimise the design so reducing the need to more ventilation equipment than is necessary.
How will the supply air be circulated through this space? Natural and Mechanical ventilation systems can simulated to demonstrated air flow and heat transfer supporting accurate window ventilation and mechanical design.
