Sparkplug with Cross-Flow and Electrode Ablation

June 1st, 2017 spark-plug-thermal-arc-simulation-vizspark

The VizSpark software is used to perform a 2-D simulation of a model spark plug channel with cross-flow. Coupling between arc physics and conjugate heat transfer to the electrode was performed. The ability to predict spark restrike events was also demonstrated. Furthermore, an estimate of electrode ablation is also made. The spark plug has been a reliable source of ignition for well over 100 years.  The ignition source plays a pivotal role in the efficiency […]
