The appearance of a substantial potential difference in a dielectric liquid (∼1000 V) flowing through a tube 6 mm in diameter was observed using metallic electrodes situated along the flow. The effect was called hydroelectric. According to the oscillograms obtained, the electric signal was high-frequency, could not be synchronized, and the potential difference between the entrance and exit of the capillary reached 200 V for positive pulses and 700 V for negative pulses. The potential difference decreased as the temperature of the liquid increased to 30-35°C and hydrostatic upthrust grew. A mechanism of the appearance of potential difference based on the predominant role played by electrokinetic phenomena was developed. [ABSTRACT FROM AUTHOR] |
