Reference area for drag coefficient calculation

  Hello, I'm running a simulation of a rotating wheel with inlet air at different angles: 0, 3, 5, 8, 10, 20, 30 degrees. At zero degrees, I understand that the reference area is the frontal area of the wheel. If the fluid domain is rotated to 5 degrees for example to simulate a cross-headwind, would the reference area change to the surface area directly inpacting the flow at that angle? So essentially, the projected area if viewed from 5 degrees? Or would it stay the same as the wheel is still going straight? n

  Yes, you should consider the projected arean
