In this work we present a study of the dynamics of premixed flames in externally heated narrow circular channels. The use of a simplified model (constant-density, one-step chemistry) permits to carry out a global stability analysis in addition to time-dependent numerical simulations. We find a rich dynamics, with oscillating flames and cellular structures as well as chaotic flame dynamics.
