Abstract: It was shown that at 298 K and 100–300 Torr, the flame front of a well-mixed dilute methane–oxygen mixture, propagating to the ends of hollow cylindrical and conical obstacles, does not form a vortex shedding behind them; however, under the same conditions, this instability occurs when hot products flow behind the obstacles.

Keywords: methane combustion, instability, vortex, obstacle, cylindrical, conical, low Mach number, Navier–Stokes equations.
