COANDĂ EFFECT AND JET FLOW

PDF datasheet

An experimental module for use with the AF10 Air Flow Bench to investigate the effect of a jet attaching to an adjacent wall examining the Coandă effect evaluation of attachment and separation and demonstration of a fluidic switch/flip-flop (fluidics).

COANDĂ EFFECT AND JET FLOW

This module consists of an aerodynamically shaped nozzle from which a jet of air emerges. This flows against a wall to which it attaches. The wall may be rotated to show the deflection of the jet through large angles due to the Coandă effect.

A second wall may be introduced at the other side of the jet, which may be switched from one side to the other, as is done in a fluidic flip-flop type switch. The effect of sealing the walls and adding a central splitter to the device are also investigated.

  • Demonstration of the Coanda effect.
  • Demonstration of the fluidic flip-flop.

Henri Coandǎ: Coandǎ Effect

Today we celebrate the contribution that Romanian Inventor Henri Marie Coandǎ made to the world of science and engineering, particularly in aeronautics. He defined the Coandǎ Effect in relation to jet deflection and was a world respected aircraft designer during the early 20th century.
