What is skin friction in aerodynamics
What is profile resistance?
The composition of the total resistance as shown below:
Thanks to DRAGBUSTERS ... This document can solve this question and analyze the air resistance in detail.
Profile resistance definition: The Profile drag is the drag created by the frictional drag of the blades flowing through the air. It does not change significantly with the angle of attack of the wing section, but increases moderately with increasing airspeed. Taken from here.
Definitions of Profile resistance as in dictionaries:
That part of the wing drag that is due to friction and turbulence in the fluid that would be missing if it were not viscous
The part of a wing or aircraft's drag that results directly from its profile and skin friction (ie, the part that is not attributable to lift).
By reading this ... (in the fifth paragraph)
Definition of form resistance: The Resistance, which depends on the shape of the aircraft is called Designated form resistance .
The following definition has been adopted from here.
Profile resistance or sometimes also called form drag, is the drag caused by the separation of the boundary layer from a surface and the wake created by this separation. It mainly depends on the shape of the object. Form or pressure resistance is caused by the air flowing over the aircraft or the airfoil.
Finally, the most common types of drag are:
Parasitic resistance, consisting of
Form resistance which is the result of aerodynamic drag due to the shape of the aircraft,
Skin friction resistance due to the smoothness or roughness of the surfaces of the aircraft, and
Interference resistance, which can occur when surfaces with different properties meet (e.g. wing and fuselage).
Induced resistance, which is a secondary effect of the generation of lift, and
Wave resistance, which comes into play when shock waves occur near the aircraft surface in transonic and supersonic flight.
Taken from this Skybrary article which describes the types of resistance very well.
