Abstract

In this work results of the laser visualization of the gas bubbles flow in a needle-to-cylinder pulsed discharge reactor filled with distilled water are presented. The experimental setup consisted of a pulsed discharge reactor, high voltage supply, CuBr laser, and Video camera. In the glass reactor bottom a stressed needle or a set of needles were placed. The grounded cylinder was set 45 mm above the needle electrode(s). The pulses of positive voltage (up to 31 kV) with a repetition rate of 50 Hz were used. A laser beam emitted from the CuBr laser was formed, using a telescope, into the laser sheet, which crossed the reactor in a selected vertical and horizontal plains. It was observed that during the positive pulsed discharge in water the bubbles production and the streamer size increased with increasing applied voltage. Large vortices generated during the discharge distributed bubbles in the whole reactor volume, providing good mixing and distribution of active species. The more needles were used, the larger number of bubbles were observed.
