Application of waveguide sensors for registration of pressure in the near zone of underwater spark and corona discharges. 1. experimental investigations

摘要

The possibility of pressure measuring with the help of piezoelectric waveguide sensors (PWGS) in the near zone of underwater spark discharge (USD) and corona discharge (CD) in water electrolites with high values of the electrical conductivity was studied. The sensors used were distinguished by their dimensions and the wave guide material as well as by their screenning. Comparison of the pressure osciliograms obtained with the use of the PWGD and the microsensor operating on the principle of volume action (Synany sensors) was conducted. Experimental data on the pressure distribution in water obtained with the use of the PWGS for USD and CD including the plasma region are presented.
