Talk:Turbulence modeling

From Wikipedia, the free encyclopedia

I think the eddy viscosity was proposed by Boussinesque. --Vladimír Fuka 16:11, 10 April 2006 (UTC)

I thought l is the mixing length, NOT necessarily the distance to the wall. Prandtl proposed that l = k*y, where y is the distance to the wall. I believe this equation might be incorrect as is; it should not have the factor k in it. I'm using Mills: Heat Transfer, specifically the section on turbulence modeling (5.5 - equation 5.120).

Yes I confirm, the eddy viscosity was proposed by Boussinesque. l is the mixing length, NOT the distance to the wall. Prandtl proposed that l = kappa*y, where y is the distance to the wall and kappa=0,4. The equation in "wikipedia : turbulence modeling" IS INCORRECT; it should not have the factor kappa in it.

[edit] This article and the section in the CFD article

This article should probably by integrated with the section on turbulence models in the article on computational fluid dynamics. -- Ehdr 18:52, 16 March 2007 (UTC)
