The intent of this study is to adapt a general numerical model of fires within an enclosure to a specific experimental test facility. The test facility is operated at the Naval Air Warfare Center China Lake, California. The research facility is in the process of studying missile fuel fires in a surface ship combatant setting. The numerical method employed is capable of generating temperature, velocity, pressure, and density fields for a three dimensional rectangular enclosure. This study is considered preliminary in that much of it concerns the treatment of various difficulties encountered in trying the model a fire with a solid rocket propellant energy release rate using the given computer code. The specific objectives of this thesis are to subject the model to a very high heat input rate and derive results for both a closed and open compartment. To analyze the open compartment it was necessary to modify the code to incorporate a vent in one of the enclosure walls. A National Center for Atmospheric Research graphics program is used to present isotherm and velocity distribution results.
