VALIDATED NUMERICAL MODELS FOR THE CONVECTIVE EXTINCTION OF FUEL DROPLETS (CDFD)

A transient numerical model was developed to study the combustion of suspended and moving droplets. This study is of immediate relevance to aviation and aeronautical personnel, especially those involved in flight operations. The experiments being conducted allow investigators to gather data for comparison with theoretical predictions of burning rates, flame structures, and extinction conditions. The present state of knowledge on convective extinction of fuel droplets derives from experiments conducted under normal gravity conditions. However, any data obtained with suspended droplets under normal gravity are grossly affected by gravity. The need to obtain experimental data under microgravity conditions is therefore well justified and addresses one of the goals of the National Aeronautics and Space Administration's Human Exploration and Development of Space microgravity combustion experiment.
