CAVITATION BUBBLES

MAIN FEATURES

  • Selection of an unlimited number of bubbles for each analysis
  • Description of each bubble through initial conditions (pressure, density, temperature, radius)
  • Definition of adiabatic and polytropic indices
  • Computation of characteristic quantities (density, temperature, entropy, heat, radius) as a function of pressure
  • Computation of characteristic quantities (pressure, temperature, entropy, heat, radius) as a function of density
  • Computation of characteristic quantities (pressure, density, entropy, heat, radius) as a function of temperature
  • Computation of characteristic quantities (pressure, density, temperature, entropy, heat) as a function of radius
  • Identification of stability conditions for bubble growth
  • Analysis of cavitation effects
  • Comparison of analytical results with available field data
  • Visualisation of results
  • Suitable for designing and testing
