Abstract
The article describes experiments with wall-mounted air terminal devices. The airflow from an air terminal device will influence the occupants` thermal comfort and it is therefore important to develop an expression for this flow. The velocity at the floor is influenced by the flow rate to the room, by the temperature difference and the type of diffuser. The flow is stratified at large temperature differences. The article shows the development of a semi-analytical expression for the velocity distribution in the vicinity of the floor. It is shown that openings between obstacles placed direct on the floor will generate a flow similar to the air movement in front of a diffuser. A semi-analytical equation for the velocity distribution is also given in the article. (au) (13 refs.)
