SD-95-18-5 -- Guidelines for CFD Modelling of Atria ✓ Most Recent

Highlights the factors that should be considered when applying computational fluid dynamics (CFD) to atrium design and gives practical recommendations on how to achieve accurate results. First reviews established CFD methods of relevance to atrium design such as using CFD results to thermal comfort and ventilation efficiency plus modelling boundary conditions for flow and heat transfer. In addition, presents new results from investigations into different ways of modelling solar radiation, ways of defining boundary conditions for wall heat transfer, the effect of near-wall grid resolution and the effect of including surface-to-surface radiation exchange. A CFD code with a conventional kappa-epsilon turbulence model was used in the study.
