For the particle model, we re-express Eq. 8.10 in terms of electrical contact and current flow (through the particle interfaces), characterized by fluxes in and out of particles, as

(8.11)

where is the contact area associated with the particle pair (ij), , and is the number of particles in contact with particle i. Assuming that the current flows in and out in a radial manner, see Fig. 8.3.

Fig. 8.3Left: current exchange between particles. Right: The particles in contact with the walls are assumed to become fully electrified and to attain the magnitude of current in the wall as well as the temperature of the wall. From particles that contact the walls, the current flows radially to contact pairs
