Effect of Spanwise Instabilities on Hypersonic Flows. Tumuklu, O. In AIAA AVIATION FORUM AND ASCEND 2024, 2024. AIAA Paper 2024-3834. _eprint: https://arc.aiaa.org/doi/pdf/10.2514/6.2024-3834doi abstract bibtex This study investigates hypersonic Mach 7.1 flows with varying unit Reynolds numbers of 5.2E+4, 1.04E+5, and 4.14E+5 1/m over a double wedge with wedge angles of 0/30◦, 5/30◦, and 30/45◦ using both 2D and 3D configurations. Significant influences of wedge angles on shock interactions, flow dynamics, and surface parameters are observed. A detailed analysis of the temporal characteristics of the flow and surface fields is carried out. The characteristics of self-induced spanwise instabilities in the relatively large separation region are closely examined. Increasing the wedge angles led to a nonlinear increase in spanwise instabilities.
