EFFECTS ON TEMPERATURE AND VELOCITY DISTRIBUTION DUE TO APPLICATION OF PULSED CORONA DISCHARGES IN LIQUID-PHASE ETHANOL
RÉSUMÉ
The effect of pulsed electrical discharges generated in liquid-phase ethanol was analyzed experimentally and computationally. A pin-to-plate reactor was chosen due to its simplicity and effectiveness in producing high electric fields, where 30 kV positive high voltage pulses with microsecond rise times were generated. It was found that pulse frequency has a significant effect on the size of the plasma discharge. Frequencies of > 400 Hz produced a shortening of streamers in addition to a rise of the temperature during treatment of ethanol. Numerical simulations show that the electric field increases the mixing inside the reactor leading to a more uniform temperature profile.
