What is Coand's effect?

Coanda effect states that the fluid or gas stream will embrace a convex outline when it is directed to a tangent to this surface. This was discovered in the 30th of the Romanian name Henri-Marie Coanda. What is unusual about the Coand effect is the fact that the fluid or gas flow is so pulled by a curved surface. The concave curve naturally pushes the flow, but the fact that convex would respond so strongly to liquid or gas is unusual. This feature is particularly important for aircraft design.

This principle was discovered and tested by Coanda on the plane. He studied his plane for more than 20 years to prove that the air along the wings of the aircraft would be diverted down due to the wing shape. The air leaves the wing, pushing the plane up and lifting it. This movement naturally results in the effect of Coand. With Coand Thruster, the air is fired from the front of the body and connects the kpovrch from the current to the upper surface. The attached air that flows in the sheet is called the Coanda nozzle that flows toward the rear partThruster. This results in suction of large amounts of air from the surrounding atmosphere. Instead of positive air pressure on the front and negative pressure on the back, the opposite of the pulling occurs, which is also known as the move.

Another important application of Coanda effect is in the technology of the circulation wing. The coanda surface is created from a short straight surface of the levitation device. The aim of the wing technology of the control wing is to use the surface and slits to replace the elevator devices at the edges of the wing. The first use of this app was on the Boeing 707.

Because all Coanda effects include a liquid object that flows through a firm, science behind this effect is known as fluid dynamics. Liquid dyanamics represents the movement of liquids or gases. The study of this science can lead to many subsequent discoveries, such as Coanda.
