DETERMINATION OF TEMPERATURES IN OSCILLATING BUBBLES: EXPERIMENTAL RESULTS

Vokurka K.
pages 615 - 618, full text

The surface temperatures of the plasma core at the final stages of the first contraction phase of spark generated bubbles oscillating under ordinary laboratory conditions in a large expanse of water are determined experimentally. The measurement method is based on the analysis of optical radiation from the bubbles and on an assumption that the plasma core is radiating as a black-body. It is found that the maximum surface temperatures of the plasma core range from 4300 K to 8700 K and these temperatures decrease with a bubble size.
