Direct Numerical Simulation for Shock Interaction with Applications to Supersonic Cavity Flows

Faculty #87
Discipline: Technology & Engineering
Subcategory: STEM Research
- Tuskegee University


This work presents the numerical study of high-speed flow over an open cavity. The high-resolution numerical method based on WENO scheme is implemented to investigate the complex flow details in and over the cavity in terms of separation followed by vortex formation ahead of the leading edge of the cavity, shear layer over the cavity, the circulation in the cavity and the upstream propagation of disturbance waves. The WENO method used in this study is the modified third-order version which minimizes the inherent dissipation of the fifth-order classical WENO. The artificial boundary conditions are used at the inflow, outflow and far-field to avoid spurious waves in the flow domain as a result of truncating the domain into finite size and acoustic waves crossing the boundaries. The preliminary results obtained from the improved version of the WENO method provide flow details promisingly with no spurious waves. The characteristic behavior of the upstream acoustic disturbance is also compared with the experimental schlieren.
