Latest developments in potroom building ventilation CFD modelling

摘要

In a context of production increases and proactive management offuture health regulations, optimised workshop ventilation isnecessary. Accurate predictions are required in order to achievecost-efficient ventilation design including all specific features ofthe building, and this involves developing complex CFD models.The complexity of the models must, however, be well adjusted.They have to fulfil requirements as different as, for example,providing precise simulation of the impact of ventilation on cellcooling or determination of the positions for roof-vent monitoringequipment. A new approach is now considered, based on thedevelopment of several CFD tools of varying sophistication.Depending on project requirements, a combination of tools withthe most appropriate level of complexity can be selected so thatthe trade-off between accuracy and computation time isoptimised. This approach, validated through comparison withmeasurement campaigns, can now be used for cell developmentand new projects, regardless of building design and localconditions.
