Numerical study on an atrium by means of macroscopic model and k-e turbulence model.

In designing air-conditioning systems for large-scale indoor spaces, it is important to predict the air velocity and temperature distributions in such spaces to enable indoor climate to be controlled effectively. The indoor climate can be predicted by two numerical simulation methods: one is a rough study by using a macroscopic model and the other is numerical simulation based on a turbulence model. Each method has its own limitations.
