Abstract

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.
