Hypothesis: Nanofluidic systems provide an emerging and efficient platformfor thermoelectric conversion and fluid pumping with low-grade heat energy. Asa basis of their performance enhancement, the effects of the structures andproperties of the nanofluidic systems on the thermoelectric response (TER) andthe thermoosmotic response (TOR) are yet to be explored. Methods: Thesimultaneous TER and TOR of electrolyte solutions in nanofluidic membrane poreson which an axial temperature gradient is exerted are investigated numericallyand semi-analytically. A semi-analytical model is developed with theconsideration of finite membrane thermal conductivity and thereservoir/entrance effect. Findings: The increase in the access resistance dueto the nanopore-reservoir interfaces accounts for the decrease of short circuitcurrent at the low concentration regime. The decrease in the thermalconductivity ratio can enhance the TER and TOR. The maximum power densityoccurring at the nanopore radius twice the Debye length ranges from several todozens of mW K$^{-2}$ m$^{-2}$ and is an order of magnitude higher than typicalthermo-supercapacitors. The surface charge polarity can heavily affect the signand magnitude of the short-circuit current, the Seebeck coefficient, and theopen-circuit thermoosmotic coefficient, but has less effect on theshort-circuit thermoosmotic coefficient. Furthermore, the membrane thicknessmakes different impacts on TER and TOR for zero and finite membrane thermalconductivity.
