    Abstract : Influence of flow compressibility on propagation and stability of premixed laminar flames in gaseous combustible mixtures has been investigated. A linear analysis of the intrinsic hydrodynamical instability of a planar flame front has shown that the instability growth rate is very sensitive to the compressibility effects and can increase significantly even for rather small Mach numbers of the flame generated flow.
