shows the thermoelectric power output readings with
respect to flow rate for TEG operation with varying insert panel
density and without flow impeding inserts. Each continuous line
represents a fitted curve for constant values of the panel density
variable (Dp) with a minimum reliability of 95.5%. It is observed that
output power increases with increasing volumetric flow rate per
channel and with an increase in panel density. Pertaining to the
results illustrated in the following Figs. 6 and 7, the measuring instruments
used in this study detailed in Section 2 yield a power
output reading with a maximum error of 0.45%.
