Definition of Interference Drag
Interference drag refers to the drag generated when two or more airstreams collide and create eddy currents, turbulence or restrictions to the smooth flow of air. This type of drag is caused by the interference between two or more objects or surfaces that are in close proximity to each other.
Interference drag is a significant issue in designing efficient aerodynamic systems such as aircraft, race cars, wind turbines, and other vehicles with streamlined designs. It is a complex phenomenon that involves multiple factors, including the angle of attack, the shape of the body, the speed of the currents, and the distance between the objects.
Interference drag can make a significant contribution to the overall drag of a system, particularly in situations where aerodynamic efficiency is crucial. Engineers and designers work to minimize interference drag by optimizing the design of the system and its components, such as the positioning of winglets, the shaping of the fuselage, and the use of vortex generators.
In summary, interference drag is a type of drag generated by the collision of airstreams that results in eddy currents, turbulence, or restrictions to smooth flow. It is a crucial factor in the design of efficient aerodynamic systems and is minimized through careful design and optimization.
