AF16 COANDĂ EFFECT AND JET FLOW Teaching Equipment Aerodynamics Trainer
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 Coandă effect • Demonstration of the fluidic flip-flop
