Simulation of Electric Field in Co-Field Treatment Chamber Using FEM

Abstract:

The technique of pulsed electric field is used for killing microbes causing food spoilage. This paper presents the calculation of electric field in co-field treatment chamber with the elliptic insulator type by the finite element method. The chamber diameter is 5 mm, and the insulator gap is 6 mm. The length of high-voltage electrode and the height of insulator were varied. The results show that too short voltage electrode length can generate high electric field spot at the junction of electrode and insulator. Increasing insulator height by 0.01 mm can decrease the maximum of the electric field by 1 percent. The results suggest that the dimensions of electrode and insulator are important to investigate the electric field for eliminating microbes.
