The maximum velocity in the occupied space is an important aspect of the thermal comfort. The velocity field is controlled by the position of the inlet devices, the introduced momentum flux and the thermal load of a room. Isothermal room air flow velocities depend on the position of the inlet devices and the introduced momentum flux only. Increasing the thermal load of the room leads to a more and more unstable flow situation. Finally, the flow field is dominated by buoyancy effects and it develops a new stable flow structure.
