| Zusammenfassung | In this work, we investigate the pressure wave and the hot gas kernel originating from a low energy electrical discharge. A phase averaged schlieren setup was employed to determine the radii experimentally through analysis of the intensity profiles. The radial locations were also calculated using one-dimensional numerical simulations of the processes following the discharge. The fraction of rapid gas heating was considered by introducing an efficiency factor for the discharge energy. By comparison of the measured and simulated extensions of the kernel the efficiency of the discharge could be estimated. |
