WebIn fluid dynamics, the drag coefficient (commonly denoted as: , or ) is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment, such as air or water. It is used in the drag equation in which a lower drag coefficient indicates the object will have less aerodynamic or hydrodynamic drag. The drag … WebCourses: Aerodynamics, Compressible Flow and Propulsion Duties: Instructed and supervised wind tunnel experiments, assisted students with airfoil model construction, …

As mentioned, the drag equation with a constant drag coefficient gives the force experienced by an object moving through a fluid at relatively large velocity (i.e. high Reynolds number, Re > ~1000). This is also called quadratic drag. The equation is attributed to Lord Rayleigh, who originally used L in place of A (L being some length).

This force is normal to the plane formed by the velocity and axis of rotation. The Magnus force causes a spinning sphere to deflect toward the direction of the motion at the front (stagnation point) of the sphere.
