Bioenergy Recovery for TEP Device of Various Nanofluids

Jung-Chang Wang

A TEP (thermoelectric pipe) device was constructed graphite electrodes, Teflon material, and stainless steel tube involving nanofluids as electrolyte. Both of heat dissipation and power generation were carried out through the thermal-electrochemistry effect of nanofluids. Water based nanofluids inside the TEP device were employed for the intentions of cooling function and bioenergy recovery simultaneously. The results revealed that the titanium dioxide (TiO2) water based nanofluid had the best thermoelectric performance and suspension stability properties among these water based nanofluids of TiO2,aluminum oxide (Al2O3), and zinc oxide (ZnO). And thethermalconductivity and power density empirical formulas of the TEP device were derived through the intelligent dimensional analysis and evaluated at a temperature between 20 and 40 °C and 0.5 to 5 wt.%
