TY - EJOU AU - Tian, Hao AU - Zheng, Yongkang AU - Zhang, Hanxin TI - A Numerical Study on Supersonic Combustion Optimization Based on the Streamwise Vortex-Couple Method T2 - Fluid Dynamics \& Materials Processing PY - 2023 VL - 19 IS - 1 SN - 1555-2578 AB - In this paper, some typical methods to promote mixing in supersonic combustion are reviewed, and the fluid-dynamic mechanism underpinning the development of the supersonic shear layer in the presence of a streamwise vortex is analyzed through computational fluid dynamics. It is proven that the streamwise vortex-couple method is an excellent approach to enhance mixing. A specific combustor design is proposed accordingly.
