The Coanda Effect

  • Chapter
  • First Online:
Modeling Multiphase Materials Processes

Abstract

Attachment of flow to a wall or walls placed around the flow is usually referred to as the Coanda effect [1]. According to Kadosch [1,2], this effect was first reported by Young in 1800. Since then many investigations have been made on its impact in a variety of flow fields [3,4,5,6]. In particular, the application to flow control in pneumatics and hydraulic circuits has been extensively investigated [3,6]. Kirshner [1] identified the following effects on wall attachment in fluid amplifiers.

  • Changing position of walls

  • Diverging walls

  • Single-sided case

  • Mean flow and fluctuation

  • Secondary nozzles

  • Pressure distribution

  • Wall height and aspect ratio
