Hi, I am currently conducting an investigation into the aerodynamics of a human powered vehicle such as seen here http://www.speed101.com/photos.htm
My aim is too closely match a published figure for a certain HPV of Cd=0.045
I am having some issues currently, my console is giving me limited tubulent viscoscity problems.
Could someone please suggest if any of my input conditions seem off?
Sparat Allmaras Model
Velocity=32.25 (0 yaw)
Turb viscosity ratio=5
Turb intensity=0.01 (value as seen, this means 1% right?)
Length scale 20m (half the domain height)
velocity scale = 0.4m/s
Im using a trimmer mesh, the object is close to the ground, no rotating wheels. I am using a wind tunnel type domain with slip walls as the far field boundaries.
