The TE power generator is assumed to be infinite along the
direction of the fins (z-axis) and the problem is considered
geometrically and thermally symmetric along the x direction.
In Fig. 7, the scheme represents a transversal cut of our system.
According to this geometry, we used a 2D simulation with the
heat transfer module. The mathematical model for heat transfer by
conduction isrC vT=vt VðkVTÞ¼q, where T is the temperature,
r is the density, C is the heat capacity, k is the thermal conductivity,
q is a heat source or heat sink, V is the gradient.
