It is important to note that beyond a threshold flow rate of 5 L/min/ch, the maximum net thermoelectric power output is obtained without any flow impeding inserts. Prior to this threshold flow rate, net power output is greater when TEG operation includes flow impeding inserts. An error analysis resulting from the instruments’ measuring tolerance (detailed in Section 2) yields a maximum error of 4.52% for the following net thermoelectric power output results.
