Hi,I'm Tomy
I have a question on the wing simulation.
I am in a simulated naca0012.
Re=3000000
Chord length= 1 m
angle of attack=18
unsteady
Turbulence:S-A model
SOLUTION:SIMPLE
Turbulence intensity =2.5%
Length scales=0.07
Reference zone:inlet
area:1m
I calculated results AOA=18
Cd=0.1
but theoretical value=0.0304
Great error
so where else to ask you to pay attention to ?
