Chelikani [18] used numerical simulation method to demonstrate that the Coanda effect would influence the trajectory of fine fibers created by the melt-blown process.
Also, modern trash rakes are used by various hydroelectric plants, and can include advanced features such as the Coanda effect, wedge-wire screens, cleaning robots, etc.
With a problem to solve, Dyson engineers used the Dyson's fast, high-pressure digital V9 motor to harness a phenomenon known as the Coanda effect, which occurs when a high-speed jet of air flows next to a surface, and, due to differences in pressure, the airflow attaches itself to the surface.
Your PS399 is buying you 'The Coanda Effect', which may sound like a bad Tom Cruise film, but is actually a high-speed air jet that wraps your hair around the curling barrel.

Although superficial similarities might be noted between the surveyed and the present works, the authors know of no literature or working concept to date that specifically exploit the combined mechanisms of the gravitational effects of a rapidly rotating vortex flow on different-density gases and the Coanda effect to achieve the proposed simultaneous charge confinement and stratification in premixed-charge engines.

Except for the spray interaction and the Coanda effect, it is the different internal flow characteristics inside the two nozzles that attributes to the deviation between the two kinds of spray properties [14].
Because of the Coanda effect from both the structural floor below and raised floor above, the air would rifle with little induction out to the UFT, providing colder inlet air.
Another option is to use energy efficient nozzles, which reduces air consumption by at least 50%, but uses the coanda effect to entrain the ambient air to increase the overall flow and volume of the air jet.
