The ERCOFTAC Knowledge Base Wiki Home Page

Welcome to the world's foremost repository of structured knowledge and advice designed to underpin quality and trust in the industrial application of CFD. The Knowledge Base was originally developed by the EU Network on Quality and Trust in the Industrial Application of Computational Fluid Dynamics (QNET-CFD). After the end of this EU network, the Knowledge Base was passed on to ERCOFTAC with the remit of making it public and to expand it continuously (see News link below). The Knowledge Base consists of individual test cases which are application centred, facilitating the identification of appropriate knowledge and advice for specific industrial purposes. They are organised around: Application Areas These are sector disciplines such as Built Environment, Chemical and Process Engineering, External Aerodynamics, Turbomachinery, Combustion and Heat Transfer, Environmenta Flows, Biomedical Flows etc. Underlying Flow Regimes (UFR) These are generic, well-studied test cases capturing important elements of the key flow physics encountered across the Application Areas. Direct Numerical Simulations (DNS) These are test cases providing statistical data from high-fidelity calculations, primarily Direct Numerical Simulations but also near-DNS Large Eddy simulations, aimed for testing and improving models for the turbulent motion and for gaining insight into this (DNS cases are coming soon)
