Three Workshops on CFD Uncertainty Analysis were organized in Lisbon in October 2004, 2006 and 2008. They were dedicated to Solution Verification (all 3 editions), Code Verification (2nd and 3rd edition) and Validation (3rd edition) for two 2-D, statistically steady, incompressible turbulent flows from the ERCOFTAC Classic Database.  Code Verification was performed with Manufactured Solutions including the turbulence quantities of several eddy-viscosity turbulence models. The Proceedings and all the information about this series (common grids of the first edition, inlet conditions and Manufactured Solutions for Code Verification) are available on-line at the following address: www.maretec.ist.utl.pt/html_files/CFD_Workshops.htm.

A follow-up of these Workshops is proposed for the ECCOMAS CFD 2010 Conference by organizing two mini-symposia, one being set up as a workshop, the other as a paper presentation session:

V&V I:        Code Verification (MMS), Solution Verification and Validation (ASME V&V 20)  for three test cases:

a)      The flow over a hump with no boundary-layer control (Case C-83 of the ERCOFTAC Classic Database also available at http://cfdval2004.larc.nasa.gov/case3.html).

b)      Flow past a square cylinder close to a wall with no vortex shedding (“Experimental Study of the Turbulent Wake Flow behind a Square Cylinder Near a Wall”, Wu K., R.J. Martinuzzi, ASME, Fluids Engineering Division, Nº FEDSM97-3151, June 1997, Summer Meeting, Vancouver).

c)      Flow past a square cylinder close to a wall with vortex shedding (“Influence of wall proximity on vortex shedding from a square cylinder”, R.J. Martinuzzi, S.C.C. Bailey, G.A. Kopp, Experiments in Fluids 34 (2003) 585–596).

V&V II:     Contributions on Verification & Validation.

Contributions for either of the Mini-Symposia should be submitted, with the header V&V I or V&V II in the title of the paper, via the Web page of the Conference (ECCOMAS CFD 2010) respecting the deadlines of the Conference. Extra information for the V&V I exercise is given in these pages:

 

1.     Flow over a hump

 

2.     Flow past a square cylinder close to a wall with no vortex shedding

 

3.      Flow past a square cylinder close to a wall with vortex shedding
