利用钝体稳定火焰实验台，在不同工况下，测量了含水蒸汽的甲烷预混气的火焰吹熄速度.结果指出，在甲烷流量和水蒸汽流量一定的条件下，当钝体表面喷涂有催化剂时，将在表面处发生催化重整反应，产生部分氢气，从而使得火焰需要在更大的空气流速下才会被吹熄，有效地提高了火焰的稳定性.在改进SIMPLE算法的基础上，通过数值计算合理地模拟了该问题的实际情况，计算结果与实验结果在定性和定量的水平上都基本符合.
The flame blowout velocity of methane pre-mixed gas containing water vapor was measured under different working conditions by using a bluff-body stable flame test bench.The results show that when the methane flow and water vapor flow rate are constant, Catalyst, the catalytic reforming reaction will occur at the surface, resulting in partial hydrogen, so that the flame needs to be blown out at a larger air flow rate, effectively improving the flame stability.Based on the improved SIMPLE algorithm The numerical simulation reasonably simulates the actual situation of the problem. The calculated results and the experimental results are basically in accordance with the qualitative and quantitative levels.
