The goal of this work is to investigate the ability of three eddy viscosity turbulent models, the standardk-?, the RNG k-? and the k-?, in predicting the three-dimensional airflow in a room under forcedconvection. The experimental data from Nielsen (1990), which represents a large room where the airenters horizontally at the top of one side and leaves the room at the bottom of the opposite side, wasused to validate the models. The mean velocity and the turbulence intensity profiles for Reynoldsnumber of 5,000 are presented in two planes of the room with two inlet arrangements.
