Coanda Effect

The Coanda Effect describes how a fluid, like air or water, tends to follow the surface of an object when flowing over it. When a fluid moves near a curved surface, it sticks to that surface because of pressure differences and the fluid's tendency to stay attached due to its momentum. This causes the fluid to stay close to or stick to the surface as it flows around it, rather than separating away. This effect is important in various applications, such as airplane wing design, where it helps generate lift, and in fluid control devices like faucets and exhaust systems.
