near wall LES
hi all,
I am working on near wall LES. I am simulating a high Reynolds number (10e6-10e7) flow over a sphere. The solver I am using works only with tetrahedral cells. So we are not able to resolve the boundary layer, hence cannot calculate the wall shear stress. I am trying to somehow model this wall shear stress using the instantaneous logarithmic law of the wall on the sphere, in the region 30<y+<5000. But as logarithmic law is not valid in separated regions and also on curved surfaces, can I at all expect this thing to work? Regards, Shailesh |

Hi there,
check out the work of Ugo Piomelli on wall-layer models for large eddy simulation. Here is the link to the publications of professor Piomelli: http://www.glue.umd.edu/~ugo/research/publications.html Hope this helps, Sincerely, Frederic Felten. |
