Abstract

Electrical power density of a thermoelectric generator (TEG) with convective heat transfer on the hot and cold sides is calculated. The conversion efficiency of the generator is also presented. By assuming the power factor is temperature independent or nearly constant within a certain temperature range, the steady-state energy balance is simulated for the equilibrium working condition of the thermoelectric generator.

Assumptions:

Assume the Seebeck Coefficient is not changing with temperature or constant within a range of working temperatures. In addition, there is no heat loss to the ambient walls from the hot side to the cold side of the thermoelectric generator (TEG). All electrical resistivity is not changing with temperature. The bulk temperatures of the working fluids are fixed.
