There are three types of parasitic drag: form drag (from blunt, non-lift producing surfaces), interference drag (from mixing air flows) and skin friction.
One of the biggest innovations was the discovery that thicker airfoils could be used without sacrificing form drag, which is discussed later in this paper.
Typically, the drag forces from seawater are divided into form drag forces and skin friction (i.
The total drag coefficient consists of a form drag resistance coefficient--CR, an air resistance coefficient--CA, and a skin friction coefficient--[C.
When the broken fiber immersed in the air flow field, the fiber are principally subjected to the air drag force, the tension force, the gravitational force, turbulence fluctuation force and buoyant force and so on, for the sake of computational simplicity, in the works mentioned above, we only considered the air drag force that the influence of the other forces are neglected, the total air drag is the sum of the friction drag and form drag due to the velocity difference between air and broken fiber, the air drag can be expressed as, respectively, by the following relations (34-38):
However, form drag would be increased when the attack angle is too large.
Particles that are non-rigid, flagellated, or otherwise subject to higher-than-expected form drag because of surface features (e.
