标题: Mixing characteristics of the mixing-enhanced flame stabilizer with gaseous fuel injection
摘要: 

Compared to using traditional liquid fuels, using gas fuels such as methane and hydrogen can significantly reduce environmental pollution caused by thermal power devices. The mixing process of gaseous fuel and air is a key factor affecting the overall performance and structural compactness of the device. We studied the mixing process of gaseous fuel and air in a transverse jet and explored methods that can be used to enhance the mixing process. A mixing enhancement mechanism for a transverse jet of gaseous fuel in which a rib is added in front of the jet has been explored. The schlieren technique is used to visualize the flow field of the gaseous fuel jet. The results of flow experiment show that the penetration depth and mixing performance of the gaseous fuel jet are improved by the rib in front of the jet. In addition, the flow mechanism of tandem twin jets in crossflow has also been analyzed, including the interaction mechanism between the front and rear jets of gaseous fuel.
