CHARACTERISTIC RESEARCH AND EXPERIMENT SIMULATION OF HEATED WALL IN NATURAL DISPLACEMENT VENTILATED ROOM

摘要：

This paper reports on research about the fundamental fluid mechanics which lead to thermal stratification in a room containing sources of heat. The theoretical model of the ventilation flow stratification in such a room and the numerical results from this model are presented. The functional relationship between the non-dimensional effective vent area and the non-dimensional height of the thermal interface in the natural displacement ventilated room which contains a single heated vertical wall (such as a wall heated by solar radiation) is observed experimentally and determined that the non-dimensional lamination is independent of the buoyancy flux provided by the effective vertical wall.
