In the present problem related to safety of stationary power generation, the coupling of gas expansion and boundary layer structure in a turbulent channel flow is addressed. Recent modeling [Gruber et al., J. Fluid Mech.,
DOI:10.1017/jfm.2012.345] showed that Darrieus-Landau
instability is related to flashback of premixed hydrogen-air flames in the boundary layer of a turbulent channel flow. The present parametric study is focused on the influence of thermal gas expansion on the possibility of flashback.
