摘要：
The lean blowout experiments of the combustion stability device A （multi-vortexes-dome model combustor） have been carried out at atmospheric pressure. Compared with the device B （single-vortex-dome model combustor）, the experimental results show that the device A has a superior lean blowout performance when the combustor reference velocity is within the range from 3.50m/s to 5.59m/s （ while the liner reference velocity is between 3.84 and 6.13m/s）, and this superiority will remain stable after the inlet air flow rate reaches a certain value. In order to analyze the phenomena and experimental results, the numerical simulation method is used, and the strain rate and the cold reflux impact are employed to further explain the reason that causes the difference between the two devices’ lean blowout characteristics.
