LES 2d on flat plate in openfoam dosen' t resolved eddis
 
Hi Foamers

I study about turbulent flow over a 30 cm chord flat plate. The unpstream velocity is 20 m/ sec and to gennerating turbulene i used a 1mm block- shaped trip. The flat plate is located at mid of a ( 10 C* 4 C( top an unnder flat plate) domain. As i simulate the flow in fluent with 2 d LES i can observe turbulence eddy shaped structures but as i run the model with same grid, boundary conditions and ..., in openfoam with 2d LES smagorinsky the flow seen with any eddy - shaped structures.
If everybody have some experiences about the topic, please let me know your valuable expriences. That is about 6 months i am involved the frustrating problem and i am out of ideas.:confused:

Regards
Farmani
