Coanda Screen

How Does It Technically Work?

Flowing media have the property of sticking to flat or convex surfaces according to the Coanda effect. Example of flowing water on a spoon: If you hold a spoon in a stream of water, the water follows its curved surface and leaves it in a different direction than it came. You can feel the associated force that pulls the spoon into the jet of water. Our Coanda screens work on the same principle.

Water flows through this gap between the V-shaped wedge wires by blocking other particles. Thus, the gap width and the angle of inclination define both the capacity and the filtration performance. In addition, the curved shape of the Coanda screen helps ensure that the filtration process is accurately completed by the flow forces exerted. Unwanted particles such as sediment, rock and sticks follow the curved shape with this applied force. As a result, it provides self-cleaning.

In the design of the Coanda Screen, important parameters such as tilt angle, open gap, acceleration plate and curved screen must be taken into account. Because more gaps and high tilt angle cause poor filtration performance but high capacity. Thus, an undesirable situation occurs with ineffective filtration performance.

To avoid this poor filtration performance, important parameters such as gap, tilt angle and curve of the Coanda Screen must be calculated, designed and manufactured accurately for the best utilization of the Coanda Intake Screen. ADENCO is capable to provide accurate and customized design and manufacturing for your applications and requirements with our Coanda Screen Engineers.
