ABSTRACT
This paper presents indoor airflow and thermal environment which is formed by a cooling jet and a local heat source in a ventilated room. To illustrate the effects of the combined the plume and the jet-flow, a series of simulated values with different calculated conditions such as different buoyancy flux are analysed by Fluent simulation software. This paper presents an index θ to describe the physical phenomenon by the thermal interaction between the cold jetflow and the plume. It is concluded that if the heat source is increasing considerably, the buoyancy source will be a leading factor of the indoor thermal field, though its initial momentum is considered to be zero.
