| Abstract | Heterogeneous ignition of hydrogen at catalytic surfaces (metal oxides, etc.) is, on the one hand, the potential reason for accidental explosions in industry and atomic power plants and, on the other hand, a promising approach for advanced ignition and §ame-holding systems in aerospace applications. One of basic speci¦c features of catalytic ignition and combustion is considerable widening of fuel-lean §ammability limit [1]. As an advantage, it can be particularly used for improving pollutant emission indices of aircraft combustors and industrial power plants. Contrary to homogeneous chemistry of hydrogen oxidation in air, heterogeneous chemistry is still a hot subject of fundamental studies. Heterogeneous chemistry of hydrogen oxidation is more or less well developed only for noble-metal catalysts. For better understanding homogeneousheterogeneous mechanisms of hydrogen ignition at catalytic surfaces, further studies for simple §ow con¦gurations like stagnation and tubular §ow conditions are required. Such studies help to identify the set of governing parameters determining the conditions of hydrogen ignition. The objective of this work is to develop a two-dimensional (2D) computer code for detailed studies of homogeneousheterogeneous hydrogen ignition in the §ow over catalytic surfaces. |
