The Coandă Effect

The Coandă Effect is the tendency of a fluid, like air or water, to stick to a nearby surface and follow its contour. When a fluid flows past a curved surface, it creates a low-pressure area, causing the fluid to be drawn towards that surface. This effect is observable in various situations, such as how airplane wings generate lift, enabling flight, or how the shape of a water fountain directs the flow of water. Essentially, it's the principle that explains how moving liquids and gases adhere to surfaces, influencing their behavior and path.
