A problem about Fluent reference value
I'm solving a 3D flow around a circular cylinder case with air dielectric and LES model. However, the drag coefficient of cylinder wall doesn't match the value announced on papers.
Reference value is set as follows:
length = diameter of cylinder
area = diameter * height of cylinder; for 2D case, diameter of cylinder
velocity = velocity of inlet
viscosity = viscosity of air
Are they right or wrong?
Thanks in advance.
