Validation of a CFD model for research into stratum ventilation

In this paper experimental results are used to verify and validate a computational fluid dynamics (CFD) model based on a commercial package. The validation is used to ensure that the CFD model is able to simulate stratum ventilation. The low speed air jet is the basis for a newly proposed ventilation mode whereby jets are placed strategically around a room at breathing height level to create a layer or stratum of relatively fresher air. Case studies from three independent experiments are simulated using the CFD model to ensure that the model is able to represent the physical characteristics, such as air flow and heat transfer properties, of this type of ventilation system.
