look for Turkel preconditioning sckeme
HI all, Who know where is any article of precondtioning for viscous compressible NS equations (Turkel or vanleer scheme)? thanks

Re: look for Turkel preconditioning sckeme
See "Preconditioning Techniques in Computational Fluid Dynamics," Annual Review of Fluid Mechanics, Vol. 31, 1999 for a fairly comprehensive reiview of this subject. I find reading Turkel's review a little difficult, but it is comprehensive.
You may also want to look at various papers by C.L. Merkle, S. Venkateswaran, Y.H. Choi, and other students that worked under Merkle. For example, the following papers might prove useful: AIAA 20002251, S. Venkateswaran and C.L. Merkle AIAA 933367CP, P.E.O Buelow, S. Venkateswaran, C.L. Merkle AIAA 923437, S. Venkateswaran, J.M. Weiss, C.L. Merkle, Y.H. Choi (** I like this one especially **) J. Computational Physics, Vol.105, pp.207223, 1993, YH. Choi and C.L. Merkle (** updated version of AIAA 911652 **)
