Flow reattachment refers to the point at which a separated flow comes back into contact with the surface, typically downstream from an object that has disrupted the original flow pattern. It is crucial in understanding aerodynamic performance and can affect drag, lift, and overall flow stability in various applications such as aircraft wings, turbine blades, and automobile bodies.

Aerodynamic performance refers to the efficiency with which an object, such as an aircraft or a vehicle, moves through the air, influenced largely by its design and the reduction of drag. Optimization of aerodynamic performance is crucial for enhancing fuel efficiency, stability, and speed, making it a key consideration in engineering and design fields.

Aerodynamic Performance

Drag is a force that opposes an object's motion through a fluid, such as air or water, and is influenced by factors like velocity, surface area, and fluid density. It plays a crucial role in engineering and physics, affecting the design and efficiency of vehicles, aircraft, and various structures.

Drag

Lift is the aerodynamic force that acts perpendicular to the relative wind and supports the weight of an aircraft in flight. It is generated primarily by the wings and is a result of pressure differences created by the airfoil shape and angle of attack as the aircraft moves through the air.
