RESUMO

This work presents an experimental study of chemically inert and reactive turbulent flows in a Bluff-Body burner. The main objective is the characterization of the flow through of the measurement of instantaneous velocity fields by using non intrusive optical techniques. The techniques employed were Laser Doppler Velocimetry (LDV) and Particle Image Velocimetry (PIV), which makes possible the measurement of the transversal and longitudinal components of the flow velocity. The experimental results were compared with those obtained from a numerical simulation using a comercial computational program. The agreements and discrepancies obtained between the two experimental techniques and from experiments and computation were demonstrated and analized.
