A numerical study of a two-dimensional model for premixed gas combustion in
a narrow, semi-infinite channel with no-slip boundary condition is performed. The work
is motivated by recent theoretical advances revealing the major role of hydraulic resistance
in deflagration-to-detonation transition, one of the central yet still inadequately understood
phenomena of gaseous combustion. The work is a continuation and extension of recently
reported results over non-isothermal boundary conditions, wider channels, and lower incipient
flame velocities, closer to those of real life explosives.
