A series of fire tests was conducted to investigate the requirements for local application water mist systems to provide consistent fire suppression performance for different sizes of open pool fires. These tests were conducted with water mist nozzles arranged above square or rectangular diesel pools. The tests showed that a water mist system gives consistent fire suppression performance for pool fires of different sizes and aspect ratios if the system meets the following requirements: 1) constant nozzle operating conditions; 2) complete pool coverage by water mist sprays, 3) constant inclination angles for individual nozzles, 4) constant ratio of total number of nozzles versus the pool area; 5) constant ratio of overall spray coverage area versus pool area, and 6) constant nozzle elevation in the flaming region above the pool. The tests also showed that fire suppression performance could be improved by lowering the nozzle elevation and increasing the inclination angles of the nozzles along the pool perimeter under the experimental conditions used in this investigation.

“…Thus, the computational fluid dynamics (CFD) tools are believed to be a very good way to deal with such a problem because they allow the study of a large number of cases and scenarios at reduced cost and 60 may result in the development of generalized engineering correlations [5] and/or general design and installation rules [10]. The CFD studies undertaken in [11] and [12] remained though rather qualitative. For example, in [11], it is stated that the numerical results should be taken with great caution and that only after the models are validated can the (numerical) study be used as a design 65 tool.…”

It is in this context that we defined the aim of our work as a detailed assessment of a CFD tool, namely the Fire Dynamics Simulator (FDS), based on the experimental data displayed in [8].…”

“…However, with the advent of the Fire Dynamics Simulator (FDS) first released in 2000 [1], modeling of fire phenomena with computational fluid dynamics (CFD) tools is becoming increasingly popular. Some early computational studies [2][3][4][5][6][7] focused on studying the interaction between fire plumes and sprinkler sprays; however, without detailed knowledge of initial spray characteristics, dispersion predictions, typically quantified through analysis of volume flux to the floor, are not very satisfying.…”
