Formatted Abstract/Summary
Numerical simulations of premixed methane/air combustion in a submillimetre narrow channel between two parallel heated
plates are performed. The problem is modelled by solving the two-dimensional, transient, full Navier-Stokes equations with the
detailed reaction mechanism (DRM-19) in our in-house code (Eilmer). The effects of the inflow velocity on the flame propagation
characteristics are investigated. For a range of inlet velocities tested, flame dynamics such as flames with repetitive extinction and
ignition (FREI), chaotically oscillating flames, symmetric stable flames, slightly and periodically wobbling flames, and asymmetric
stable flames are observed.
