This work explores the Coand˘a effect through both theoretical analysis and computational simulations. A theoretical framework is first developed to understand the physical principles underlying the phenomenon. Then, Computational Fluid Dynamics (CFD) simulations are carried out to visualize and quantify the effect in two distinct configurations. The first scenario considers a jet impinging on a cylindrical object at various vertical positions, to demonstrate the existence of a restoring force. The second examines the influence of the velocity when an inlet is placed on top of the cylinder to analyze the deflection angle. Simulations are conducted in both laminar and turbulent flow regimes to assess the consistency of the observed behavior. These findings highlight
the practical relevance of the Coand˘a effect in flow control and lift generation, with applications in aerospace and fluidic device design
