Sprinklers generate a jet of downward moving gases from smoke in the upper layer of a two-layer zone within a compartment. It is necessary to determine quantitatively the jet of downward-moving gases and fire plume in order to calculate smoke behavior in a compartment with sprinkler activation. This study proposes a measurement technique of mass flow rate based on the gas analysis method since it is difficult to understand through conventional methods. Experiments were conducted on a full scale and the following results were obtained: the fire plume grows with sprinkler activation and a jet of downward-moving gases grows as the heat release rate decrease and the amount of sprinkler supplied water increases.
