Analytical Investigation of the Coanda Effect

Abstract

Analytical study was made of Coanda effect and of a Coanda device. The effect is a combination of three separate phenomena concerning increase in velocity and mass flow in a fluid, deflection of issuing stream around a series of surfaces, and entrainment of additional air by dragging stationary air along with primary jet providing additional air flow. Coanda claims the phenomenon to be applicable to thrust augmentation units, a high lift, low-drag wing, and various types of prime moves.
