The effect of location of a convective heat source on displacement ventilation: CFD study.

Author(s) : PARK H. J., HOLLAND D.

Summary

Two-dimensional computational simulations are performed to examine the effect of vertical location of a convective heat source on thermal displacement ventilation systems. A heat source is modeled with seven different heights from the floor (0.5 to 0.75 m, 1.0 m, 1.25 m, 1.5 m, 1.75 m, 2.0 m) in a displacement ventilation environment. As a heat source rises, the convective heat gain from the heat source to an occupied zone becomes less significant. This effect changes the temperature field and results in the reduction of the cooling load in the occupied zone. The stratification level is also affected.
