    Influences of Dual Air-Swirler Angles on Swirling Injection and Combustion of Kerosene-Air at a Supercritical Pressure by Danyang Wang, Danyang Wang, Dongxin Huang, Jianguo Xu, Hua Meng, Hua Meng

    Published 2025-01-01
    “…Numerical results indicate that the inner air swirler exerts strong impact on fuel-air mixing and chemical reactions inside the inner injector, leading to a Y shaped recirculating flow and a V shaped flame at an inner swirler angle of 40°. The precessing vortex core (PVC) is generated by the inner air swirling injection, and detailed analyses reveal that the PVC frequency is controlled mainly by the inner swirl number and the maximum axial velocity from the inner injector. …”

    Inflatable Leading Edge-Based Dynamic Stall Control considering Fluid-Structure Interaction by Shi-Long Xing, He-Yong Xu, Ming-Sheng Ma, Zheng-Yin Ye

    Published 2020-01-01
    “…The numerical results indicate that the ILE can change the radius of curvature of the airfoil leading edge, which could reduce the streamwise adverse pressure gradient and suppress the formation of dynamic stall vortex (DSV). Although the maximum lift coefficient of the airfoil is slightly reduced during the control process, the maximum drag and pitching moment coefficients of the airfoil are greatly reduced by up to 66% and 75.2%, respectively. …”
