Application of CFD Tools for Indoor and Outdoor Environment Design
نویسندگان
چکیده
Computational Fluid Dynamics (CFD) has become a useful tool for the study of indoor and outdoor environment problems. Recently, the Massachusetts Institute of Technology (MIT) has developed several Reynolds Averaged Navier-Stokes (RANS) equation models and Large Eddy Simulation (LES) models to enhance the capabilities of CFD for use in indoor and outdoor environment design. The new models have been successfully used to assess building shape design, to evaluate the effectiveness of natural ventilation in buildings, to model VolatileOrganic-Compound (VOC) emissions from building materials, and to calculate indoor environment parameters.

متن کاملUsing computational tools to factor wind into architectural environment design
Wind can have many positive attributes in an architectural environment such as providing a comfortable and healthy indoor environment and that can also save energy, by means of passive cooling or natural ventilation. However, wind can also cause discomfort to pedestrians if its speed around a building is too high, and it can also increase energy loss in the winter. Firstly, this paper will disc...

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...

متن کاملPsychrometric chart as a basis for outdoor thermal analysis
Preparing thermal comfort conditions in outdoor public spaces is one of the considerations of architectural design. If the constructed area does not support comfortable conditions in outdoor spaces, it will cause microclimatic problems for pedestrians and adjacent buildings. Regarding the different thermal comfort conditions in outdoor spaces in comparison with indoor, several indices have b...
