| Zusammenfassung | A sphere/sphere electrode test setup utilising low energy capacitance sparks is used to measure ignition limit curves of propane/air and ethene/air mixtures. For selected mixtures, the probability of ignition is determined by means of logistical regression. A high-speed schlieren setup is used as a reliable method for detecting ignition. Also from the schlieren images, flame front propagation velocities are derived. The results show good agreement with data published by other authors. The test setup shall be used in combination with numerical simulations in order to gain a better understanding of the physicochemical processes, especially losses, relevant to ignition at low energies. |
