  This work concerns the study of thermo-physical properties and transport
phenomena in thermoelectric liquid polyaniline sheet. The electro-thermal heat
transfer equations coupled to Naviers-Stokes equation, continuity equation,
initial and boundary conditions are solved using the finite difference and the
finite element schemes. The results of both numerical techniques show good
qualitative and quantitative agreements. The voltage difference, the
temperature variation, the Seebeck coefficient, the figure-of-merit and the
maximum efficiency of polyaniline sheet are determined numerically. Our results
show that the voltage difference is equal to 0.09 mV for non doped polyaniline
and 0.20 mV for doped polyaniline DPAN/HCl(I) for a sheet dimension of 192 mm3.
