The Coandã effect is an interesting phenomenon in fluid mechanics discovered by the Romanian inventor Henri Marie Coandã. The physics of the Coandã effect is based on the property of a jet flow to attaches itself to a nearby surface and to remain attached even when the surface bends away
from the initial jet direction. In free surroundings, a jet of fluid entrains and mixes with its surroundings as it flows away from a nozzle. The final result is the deflection of the external flow and generation of lift forces. After 2000, the Coandã legacy was valued by researchers from many countries, mostly by developments and patents in the field of small Unmanned Aerial Vehicles (UAVs).
