Quality & Reliability of CFD Simulations III: Quantifying and Reducing Uncertainty

A Joint NAFEMS - ERCOFTAC seminar

CFD is increasingly used in engineering design, safety analysis and environmental assessments. A key question which arises is the accuracy of CFD simulation, especially when test or field data for validation is sparse. This seminar brang together current and potential users of CFD to examine the quantification of uncertainty for industrial and environmental applications:
• appropriate measures by which to judge the fidelity of CFD;
• minimising uncertainty in CFD applications;
• validation;
• challenges that arise in quantifying uncertainty, and solutions.

Methodologies to obtain reliable and consistent results from CFD are of prime importance in reducing uncertainty. The seminar therefore also illustrated best practice in CFD, highlighting findings which have wider relevance and impact.

This was the third joint meeting on this theme co-organised by NAFEMS and ERCOFTAC. It followed successful meetings in March 2004 and September 2005.
