Hi, I'm looking for a good book on turbulence modelling which starts from an elementary understanding of turbulence and doesn't involve obscure mathematical notation or too complicated maths to start! I have Wilcox's book but it starts at a bit too high a level. Really looking for a good description of the k-epsilon model (with it's various modifications, e.g. for buoyancy) to start with - would involve going through each of the terms in the equations and explaining their significance and derivation.

Thanks for any suggestions.

Tennekes and Lumley's book is probably the best introduction to Turbulence you will get.

Yes, I've already got it and am reading through it.

Wilcox (1993) is also a good reference, as well as the ICASE Short Course on Tub. Modelling (1994) edited by Gatski et al.

I think the best introductory book to turbulence modelling is Rodi's, i.e.

Rodi, W., 'Turbulence models and their application in hydraulics- A state of the art review', IAHR Book Publication, Delft, The Netherlands, (1980).

There are latter editions.
