Sara GILANI, Hamid MONTAZERI, Bert BLOCKENDOI: https://doi.org/10.26868/25222708.2013.1157Abstract: Accurate and reliable CFD simulation of temperature stratification in indoor environment is needed for the design and evaluation of displacement ventilation in buildings. This paper presents a detailed and systematic evaluation of the capability of 3D steady RANS CFD simulations to predict the temperature stratification in a room. The evaluation is based on sensitivity analysis and validation with full-scale measurements of indoor air temperature. The results show that steady RANS can accurately predict the temperature stratification in an indoor environment. The SST k-ω model shows a better performance compared with other considered turbulence models. Pages: 504 - 511 Paper:
