Abstract : This paper presents an overview of results obtained in the Combustion Model Evaluation research program being sponsored by the Air Force Wright Aeronautical Laboratories. The characteristics of a bluff-body research combustor used in this program are described. Data obtained with a laser Doppler anemometer system and a coherent anti-Stokes Raman scattering system are presented. These results and those obtained with conventional probe devices and flow visualization techniques are compared to both time-averaged and time-dependent calculations of the near-wake region of the bluff-body flow field. The results of computer model experiments of the flow field for different diameter bluff bodies are also presented. (Author)
