Numerical simulation of the spark channel behavior with secondary electrical circuit model
Lagrangian particles are introduced in 3D CFD code to calculate the spark channel behavior. Secondary electrical circuit model of ignition coil is used to calculate voltage and current at the spark plug.
The spark discharge experiment is conducted at the air charged constant volume vessel. The results shows the calculated spark channel length, voltage and current are in good agreement with experimental results.
