Validation Process for CFD Simulations of Wind Around Buildings
نویسنده
چکیده
Our study is based on a great number of CFD (computational fluid dynamics) simulations to evaluate wind comfort at the pedestrian level. This article explains the method used to validate our CFD simulations carried out with the FLUENT software. This validation is based on a comparison between our simulated results and wind tunnel tests for three different building contexts: a single building, the interaction between two buildings and an urban situation. This validation allowed us to optimize the choice of various modelling parameters: grid resolution, turbulence model, etc. From this study, we worked out guidelines for numerical wind modelling in order to quantify wind discomfort levels. This article highlights the fundamental importance of validating CFD simulation tools from a configuration and a type of flow as close as possible to the subject of our researches or applications.

متن کاملNatural Ventilation: Analysis of Indoor Airflow in an Assumed Cubic Building with Opposite Openings by CFD Investigations
The natural ventilation is an easy way to exchange the indoor polluted warm air with outdoor fresh air. The wind power injects outdoor fresh air into the building. A good indoor air current and subsequently a proper exhaust depend on the openings’ conditions and their situations. A serious architectural question is under what conditions of the openings the wind-cross ventilation can be effectiv...
