Cd = Cs + Cf + Ci?

I'm confused, ive just been reading a technical SAE paper which states
Cx = Cs + Ci + Cf where Cs = shape drag coefficent (Technical paper description, i assume it means pressure drag) Ci = induced drag coefficent Cf = skin friction coefficent I assume that Cx = Cd in the x direction Is this true? I think i have been told in the past that Cd = Cf+Cs (pressure and friction components). In Starccm+ you can split the recorded Cd coeficent into pressure and shear components, but there is no mention of induced drag. |

I think that would make sense, im certain CFD software counts induced drag as a form of pressure drag (as esentially thats what it is). |
