This work investigates the development of tulip shaped flames during laminar flame propagation in a closed duct. In particular the interaction of a laminar flame front with its self-induced non-steady flow field is examined as a possible source of the tulip phenomenon. The flame generated flow is measured with a laser Doppler anemometer (LDA). The flame shape and its position are recorded with high-speed schlieren cinematography. Comparison of the qualitative schlieren and the quantitative LDA data records provides insight into the flame/flow relationship.
