Abstract

Unsteady motions of a Bunsen-type premixed flame tip with burner rotation were studied from a viewpoint of nonlinear dynamics. The mean velocity from burner tube U was varied from 0.6 to 1.2 m/sec, and rotating speed of the burner N was varied from 0 to 2800 rpm. A rich methane/air mixture (equivalence ratio φ = 1.43, Lewis number (Le) > 1) was used. Under the condition of Le > 1, an axisymmetric oscillating flame was formed between a conical flame and a plateau flame at U = 0.6 m/sec and swirl number = 1.14. As U and N increased and constant S, the oscillating flame tip motion became unstable. The flame tip motion with burner rotation under the conditions Le > 1 varied from periodic to non-periodic, i.e., to chaotic. The analysis based on deterministic chaos theory, such as correlation dimension, was valid for quantifying unsteady flame motions. Original is an abstract.
