Abstract
This report presents a comprehensive review of numerical models for the prediction of water mist fire suppression in ship compartments, details of using computational fluid dynamics tools for such problems, implementation of a one zone model in a computer program, and efforts to validate the numerical models. Several types of water mist fire suppression models were reviewed, including zone models and computational fluid dynamics models. Investigations were conducted to outline the input parameters required when simulating water mist fire suppression in two computational fluid dynamics packages, Fire Dynamics Simulator 5.3 and CFX 11.0. The simulations run using these tools illustrated physical processes not present in simulations run on the simpler one and two zone models, but required a few hours to a few days of computational run time. The zone model of Li and Chow [Heat Transfer Engineering, Vol. 27, No. 10, pp. 99-115, 2006] was implemented in a computer code named the Water Mist Fire Suppression Utility. The effect of varying input parameters on this model was assessed and the output of the model was validated against experimental data.
