Based on a state-of-the-art review, some computational results, and experimental data, a few questions one usually encounters in numerical simulation of room air movement are discussed in this paper. The following conclusions drawn are: The standard k-epsilon model is still the most appropriate detailed model used in computing room airflows, The standard k-epsilon model may correctly predict turbulent air motion in a room if the thermal and flow boundary conditions are provided properly, and it is difficult to predict unstable airflow and airflows with multiple solutions.
