説明

論文(Article)

The Peltier element has a structure in which metal electrodes, p-type and n-type semiconductors are alternately connected between two plates. When a temperature difference is applied between the two plates, a voltage is generated by the Seebeck effect. Then, we measured the output voltage generated by the temperature change in the flooded water due to convection using a Peltier element. The following results were obtained. (1) The Peltier element can detect temperature changes in the water due to convection. (2) The average and fluctuation of the output voltage of the Peltier element increased as the intensity of convection increased. (3) High positive correlations were confirmed between the averages of the output voltage of the Peltier element and the intensity of convection, and between the fluctuation ranges of the output voltage and the intensity of convection.
