how to decide coefficient of kw modeling
i am new on turbulence modeling and read Wilcox' paper named "Reassement of the ScaleDetermining Equation for Advanced Turbulence Models, AIAA j., 1998. there are many coeffients on the kw equation(IIB in the paper). i could derive beta/beta^* = 6/5 but remains of coefficients, sigma, sigma^*, gamma, couldn't. anybody who have information, tell me. i would like to know how to decide the rest of coefficients. thanks ahead.

Re: how to decide coefficient of kw modeling
(1). I don't have that paper you mentioned. I don't think it is listed in AIAA Journal,1998. (2). It is a good idea to talk to the author directly, if he has the time to answer your questions. You can find his address in Resources/ company section.(DCW ,I think)

i am sorry. i made a mistake! Reassement of the ScaleDetermining Equation for Advanced Turbulence Models, AIAA j., 1998.(< here!)
1998>1988 the correct is the Wilcox'paper, Reassement of the ScaleDetermining Equation for Advanced Turbulence Models, AIAA j.Vol26, No 11 p1299p1310, 1988. 
Re:errata!
This is a pretty old paper. Wilcox's has since then revised his model. You should get the new edition of his excellent book "Turbulence Modeling for CFD". It presents a more recent version of this model and gives a lot more details  should give you a good start.

Re:errata!
Thanks Mr. or Mrs. Larsson.
I read the book, especially p92 to p95. The book summarized his paper so the contents of the book the same.
