Spark plug electric field

Problem Type: 3D electrostatics.

Geometry: 3D import.

Relative permittivity of air ε0 = 1,
Relative permittivity of insulator εr = 5,
High DC voltage V = 15 kV.

Calculate the electric field stress distribution in the spark plug air gap.

We simulate only the area around the spark gap. The other parts of the spark plug are excluded.


Electric field distribution in the spark gap:
