Abstract
Thermally-induced plume in a chamber under forced ventilation will be studied in this paper. Plume equations derived under natural ventilation available in the literature will be reviewed first. Computational Fluid Dynamics are then applied to study two 'models' induced by a heat source in a chamber with forced ventilation. They are the parallel flow model and the jet flow model. Based on the plume expression in chambers with natural ventilation, two plume equations under forced ventilation are then derived from seven sets of CFD simulations. There are four cases on different thermal power of the point heat source; and three cases on plume in chamber with forced ventilation under three different air speeds. Symbolic mathematics are used for solving some equations concerned.
