Overview

Randomized trial demonstrates improved cavitation performance in a novel hydrodynamic reactor, indicating effective design parameters.

Key Points

  • The aim is to investigate how structural parameters influence the cavitation characteristics of a novel hydrodynamic cavitation reactor.
  • Utilized computational fluid dynamics (CFD) with the RANS framework and SST k–ω turbulence model.
  • Analyzed the temporal–spatial evolution of cavitation in response to geometric parameters.
  • Conducted parametric studies to determine optimal design ranges for blade width and rotor clearance.
  • Cavitation occurs with a strict 72° periodicity and the static pressure drops to approximately -97.8 kPa.
  • Optimal blade width of 9 mm yields the highest cavitation rate of 0.833.
  • Rotor clearance range of 5–6 mm achieves cavitation rates exceeding 0.820, improving performance by over 10 times compared to dual-rotor designs.
