Drag reduction refers to the process of minimizing the aerodynamic drag experienced by an object moving through a fluid (such as air or water). Aerodynamic drag is the resistance force exerted by the fluid on the object in the direction opposite to its motion. Drag Reduction can be calculated using the following formula:
Where,
- is the drag force,
- is the drag coefficient,
- is the reference area of the object,
- is the density of the fluid,
- is the velocity of the object relative to the fluid.
