Propagation of a hydrogen-air flame front in channels covered with porous polyurethane foam
Keywords:
combustion, hydrogen, porous coating, polyurethane, Darrieus-Landau instabilityAbstract
An acceleration of flame in a hydrogen-air mixture in a channel, the inner surface of which is covered with porous polyurethane foam, is experimentally investigated. The molar excess of the hydrogen varied from 0.3 to 1.0, and the pore size varied from 0.3 mm to 2.5 mm. The flame front propagated in a half-open channel at atmospheric pressure and room temperature. Using the Schlieren methodic and a high-speed camera, the propagation velocities of the flame front were determined depending on the pore size and composition of the mixture. The maximum recorded velocity of the flame front was 1600 m/s for a maximum pore size of 2.5 mm. The dimensions of the inhomogeneities generated at the flame front were determined. The relationship with the size of the Darrieus-Landau instability has been established. By the piezoelectric transducers, the pressure exerted by the combustion products on the lateral surface of the channel was determined. The critical Peclet numbers were found at which acceleration of the flame front and an increase in pressure behind the flame front are registered.
