The current paper introduces a facility to be used for the investigation of fire suppressant transport and pool fire extinction in an environment similar to an aircraft engine nacelle. This work is done as part of an ongoing effort to develop a suppressant transport model that could be used within the computational fire code currently under development by Sandia National Laboratory. The flow in this facility was conditioned to match airflow characteristics of typical aircraft engine nacelles and characterized using constant temperature anemometry and flow visualization. The mean streamwise velocity was found to be 6.30 m/s (20.7 ft/s) +/-10% with a nominal turbulent intensity of 5.0 % +/-1%. Flow visualization indicates the presence of a recirculation region extending upstream from the pool leading edge as well as flow being transported from the pool leading edge upstream over the clutter. This characterization will provide baseline documentation for future investigations.
