Hey!

I am trying to find some good and representative books which could guide a reader to effectively learn what are the main mathematical, physical and computational aspects of the turbulence phenomena, known at the moment on the CFD field. Especially I'm interested in LES.

I would prefer that the book/journal/article etc. is up to date and could give firstly a well established mathematical base for the model and then represent some comparison between the different implementation techniques and how they are related to experiments.

Any advice is appreciated.

Cheers

I find that chapter 3 of Versteeg's and Malalasekra's "An Introduction to Computational Fluid Dynamics: The Finite Volume Method" explains turbulent flow and their discretization in the CFD domain very well. For me it answered most of my questions and they also talk about initial conditions which is often neglected in other books. The part on LES is only 12 pages but it still covers the essentials and some advanced topics in LES, from the filtered NS equations to filter function and then the subgrid models from smagorinsky to germano's dynamic approach. they also talk briefly about applications.

if you talk about the classics, you have to include pope's "Turbulent Flows" with chapter 13 having 80 pages or so on LES, but I as a practical guide to get started with LES I would probably not recommend it. on the other hand, if a thorough mathematical description is what you are after then this is probably the book to for.

Wilcox has written a good and understandable book on turbulence, though I don't have a copy at hand to check whether or not it covers LES. If you can get your hands on it and are interested in turbulent flows then this, I find, gives a more engineering viewpoint.

Paperwise it is best to check with the annual review, they publish good papers on more general topics and are more explanatory then your average 5 page paper. two papers that i can recommend are:

• New Trends in Large-Eddy Simulations of Turbulence, M Lesieur, and O Metais, Annual Review of Fluid Mechanics Vol. 28 (1996): 45-82

• Numerical Simulation of Turbulent Flows R S Rogallo, and P Moin Annual Review of Fluid Mechanics Vol. 16 (1984): 99-137

the first one is a bit more focusing on the mathematical description with some examples given while the second also talks about computational requirements (grid resolution, boundary/initial conditions, time advancement ...)

Further to the advised Pope's book, the books of Sagaut and Lesieur cover the field of LES.

A more mathematical book about LES methodology is that of Layton.

Wilcox covers RANS modeling well, but does not give any information on LES. I found Popes book good for an overview, and would recommend Sagaut's for more details.
