| Zusammenfassung | For optimization of combustion engines understanding the ignition of combustible mixtures by electrical discharges is of crucial importance. A combined experimental-numerical approach is employed to gain deeper insight into the related physicochemical processes during the ignition by thermal and non-thermal plasmas. In both applications energies near the minimum energy necessary for ignition have been imposed. The temporal development of the plasma kernel and the shock wave measured using a schlieren method in combination with numerical simulations were used to quantify the ignition efficiency of a capacitance sparks. Radial profiles of OH radicals measured by laser induced fluorescence (LIF) were compared with numerical results to validate the numerical tools which now can be used to model ignition of advanced biofuels. Volumetric ignition by non-thermal plasmas has been investigated through numerical simulations which were used to examine the temporal development of temperature and radicals inside the plasma channel in detail. |
