Re: Mesh 2d airfoil with viscous layer

Posted by Joao Lourenco at August 12. 2017

Hey everyone,

 

I'm trying to mesh a 2D airfoil using SALOME, with viscous layer, but I have some problems meshing the leading edge.

 

I separated the airfoil in two groups:  1 group - trailing_edge and 2 group - leading_edge upper/lower_surface.

The trailing is ok because I created an fillet and meshing the trailing edge with wire discretization - Number of segments - Equidistant Distribution. For the 2 group I try the same but I need more refine in the leading_edge. I try the wire discretization - Distribution with table density but the result it isn't what I was waiting. (see image)

 

I want a viscous layer more refine in leading edge but in the upper and lower surface the squares between layers more or less with the some space. I have attach the python script I'm developing. 

 

Can some help me?

I canno't attach the image. Is to large...

Is this example of mesh satisfying You? (See attachment.) I could show You how it was done if You want to. Have a nice day. Sheaker

Hi Sheaker!

The mesh that you show me is the type of mesh that I want. Can you show me how I do it? By the way I'm using python scripts too.

Thanks a lot.

Hello. I'm sorry for late reply. In fact the mesh is looking good but it isn't working. I mean I cannot converge my simulation so I'm just about to create new mesh. Probably I will show You some screens and tops within a days. For now check this topic where I put some info about my previous mesh: https://www.cfd-online.com/Forums/openfoam-solving/192173-sonicfoam-tuto-nacaairfoil-steadystate.html Have a nice day. Sheaker
