Web1. mar 2024 · Background oriented schlieren method is applied in diagnostics of shock waves in air. The method can be used for visualization of shock waves that are generated after explosion or due to motion at ultrasonic speeds. Experimental data make it possible to observe propagation of a shock wave in space, estimate the asymmetry of energy … WebMy engineering honours thesis focused on investigating the capability of the tomographic background-oriented schlieren (BOS) technique to reconstruct the refractive index of a lifted flame. The refractive index of a turbulent methane-air flame was calculated through data obtained from a direct numerical simulation (DNS).
