Optimal performance and entropy generation transition from micro to nanoscaled thermoelectric layers

摘要: Abstract In this paper we address the heat and electric charge transport in a thermoelectric thin layer. The analysis is based on hyperbolic type equations describing time evolution of dissipative flows including size effects thermal conductivities. We explore layer width system and, particularly, figure merit entropy generation. find transition between two dynamic regimes controlled by system’s when going from micro to nanometric scale lengths. featured marked increasing total low generation regime dominated diffusive with high values wave energy transfer (this last corresponding scale). use here spectral methods solution which assure well representation behaviour given their convergence.
