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.
Learning outcomes
- Demonstration of the Coanda effect.
- Demonstration of the fluidic flip-flop.
