Simulation of the electric current flow in artificial graphite

Resumo

The electric connection of crystals in polycrystalline to locate the contact points on the surface has been simulated using the solution of the boundary problem for an elliptic equation. A chain model and the tensor components of the quasi-monocrystalline graphite conductance have been used to calculate the size of the plates artificial graphite. We consider the parameters influencing its value and the kind of temperature dependence of the specific electric resistance and evaluate the integral dissipation of electric energy along and across the layers.
