Taking the Annex 20 case as an example, simulates indoor air flow using several different turbulent models including V2F, Reynolds stress, standard K-, low Reynolds K- and RNG K- models. Compares the simulation results with experimental results obtained by other researchers. The results show that V2F model should be used prior to other turbulent models due to its good agreement with the experimental results.
