 July 30, 2001, 18:29 Exact 2D NS solution for benchmarking? #1 Tony Guest   Posts: n/a Hi there, I need an exact 2D incompressible NS solution (analytical) for benchmarking. I know that there is a 3D solution by Ethier and Steinman in Int J Num Meth Fluids. But I could not find this journal in our library. Thanks for any help. Tony

I'm sure you can order a copy from here if you want. http://www.interscience.wiley.com/jpages/0271-2091/ Prof Ethier is at the University of Toronto. Maybe he has a postscript copy on his web page. Two good books which have the analytical solutions to the NS equations are: Incompressible Flow. R.L.Panton Fundamental Mechanics of Fluids. I. Currie

You can test your solver in the two extreme limits (high Re and Stokes limit) by varying the Re. I find it useful to quantify the artificial dissipation relative to physical dissipation at various grid spacings. A Non-staggered Grid, Fractional Step Method for Time-Dependent Incompressible Navier-Stokes Equations in Curvilinear Coordinates Yan Zang, Robert L. Street, Jeffrey R. Koseff Journal of Computational Physics, Vol. 114, No. 1, September 1, 1994 If you need more complicated solutions of NS equations, look for solutions based on Lie Groups. I can not remember a reference off hand, but you search using NS equations and Lie groups and I am sure you can find something on the net or in your library.
