A thermoelectric liquid-to-liquid generator with forty thermoelectric modules is tested over a variety of flow rates and under different turbulent flow conditions defined by the panel density of flow impeding geometric inserts. For all test cases of the present study, the temperature and pressure in the fluid is recorded at the inlet and outlet of two fluid channels maintained at an input temperature difference of 70.6 Cs. The thermoelectric power generated due to the resultant asymmetric thermal field is measured for all test operating conditions.
