Boundary conditions for wind tunnel model
ello de
When setting boundary conditions for a wind tunnel with the air travelling at say 27m/s what should you set the boundary conditions at the inlet as and what should you set the boundary conditions of the air as? |
Re: Boundary conditions for wind tunnel model
for the inlet: mass-flow-inlet (mass flow depends on the density of the air) or velocity-inlet :27 m/s
for the outlet: pressure outlet with an appropiate gauge pressure (0 at outlet into atmosphere) Setting of k and epsilon is difficult... use the default settings for a first attempt. Ralf |
Re: Boundary conditions for wind tunnel model
ok but where do I set the 27m/s? as a moving mesh under boundary conditions with translational vel. of 27m/s or at the inlet boundary condition

Re: Boundary conditions for wind tunnel model
As a inlet boundary condition.
You only need moving mesh, when two solid body (or walls) are moving with differend speed or differend direction |
