Overview

Explores optimal cavitation pressure for dye degradation in simulated wastewater, suggesting a faster, effective method for industrial processes.

Key Points

  • To optimize operating pressure for methylene blue degradation in a self-excited oscillation cavity using a novel method.
  • Explored cavitation dynamics in a self-excited oscillation cavity (SEOC) using simulated wastewater.
  • Utilized image grayscale analysis and fast Fourier transform to measure cavitation intensity.
  • Established a standardized procedure for determining optimal pressure for SEOCs.
  • Achieved peak methylene blue degradation efficiency of 44.44% at 0.3 MPa in the first SEOC.
  • Found that supercavitation above 0.5 MPa led to reduced efficiency of 38.9%.
  • Indicated that vapor volume fraction is not a reliable measure of cavitation performance.
