Suppose the flow is coming at an angle on an airfoil. Is it better to make inlet boundaries with the same angle or make them straight in Gambit. In both cases we have to specify the flow at the angle given. Many Thanks.

I think the way it is normally done is to have the aerofoil at an angle - the way it would be in a wind tunnel.

When you say aerofoil does this mean you are working in 2d?

hello, Thank you for reply. i am working on a 3D airfoil (stator) of a gas turbine.

Muhammad,

There's tutorials in the Gambit documentation for meshing GT blades. If there's no moving parts it will simplify the solution procedure but you should still concentrate on the near wall treatment(dense) using boundary layers and size functions as shown in the tutorials.

There really are lots of tutorials dedicated exactly to this as it is a popular field, all in the Gambit documentation(user manual). So, I can't stress enough that I advise you to do them unless you have already done so.

PS- I don't want to sound like an arse but in the UK anyway the usual notation is that an airfoil or aerofoil is a 2D cross section whereas a stator would be a full 3D finite wing/blade/,etc.
