Text from Alexandr614 - English

  • Article

  • A fluid film is repeating profile irregularities and form the regular waves when the fluid film falling on rough surface.
  • The length of these waves (distance between nearby peak of waves) depends on the distance between nearby profile peaks.
  • Number of “standing waves” matches number of profile peak under fluid film.
  • Difference between gravity waves and “standing waves” is that the gravity waves are moving down on the free surface of fluid film.
  • “Standing waves” are not moving.
  • Position of peak and valley of “standing waves” coincide with peak and valley of the roughness.
  • Proposed structured packing has no roughness (height of profile peak smaller than the thickness of fluid film).
  • On this structured packing standing waves are appearing as a result of corrugation of the packing element.
