How to Navigate around the Knowledge Base

How to access content within the Knowledge Base

The ERCOFTAC Qnet Knowledge Base Wiki is the World's foremost repository of structured knowledge and advice designed to underpin quality and trust in the industrial application of CFD. It an interactive site aimed to guide and advice users through trusted test cases whilst encouraging and welcoming all comments and contributions.

The knowledge base is partitioned into Gold and Silver Domains. The Gold Domain is the repository for content that has been carefully checked and therefore satisfies high quality standards, available to ERCOFTAC members only. The Silver Domain is the repository for less mature content which is still under discussion and open for improvement by the public. Parts of the Silver Domain are marked as Silver . This is reserved for content which has matured to levels of quality and significance approaching Gold standard, and made public to serve as examples of the high quality found in the Gold domain. In some cases it will act to invite the addition of new CFD results obtained with alternative models.

Both Gold and Silver Domains are application centred, facilitating the identification of appropriate knowledge and advice for specific industrial purposes. They are organised around:

Application Areas

Application Areas are categories of articles of specific interest to particular sector disciplines such as: Built Environment, Chemical and Process Engineering, External Aerodynamics, Turbomachinery, Combustion and Heat Transfer.

Each Application Area is comprised of Application Challenges (AC) which are realistic industrial test cases used to judge the competency and limitations of CFD for a given Application Area.

The content of each Application Challenge (AC) test case within the Knowledge Base consists of an:

• Abstract - Summary of content
• Description - Introduction to the test case and physical phenomena
• Test Data - Description of test case experiments and provision of data for the AC
• CFD Simulation - Description of CFD Simulations and provision of results for the AC
• Evaluation - Comparison of CFD results and test case experiments evaluation.
• Quality Review
• Best Practice Advice

Underlying Flow Regimes

These are generic, well studied test cases capturing important elements of the key flow physics encountered across the Application Areas.

The content of each Underlying Flow Regimes (UFR) test case within the Knowledge Base consists of an:

• Abstract - Summary of content
• Description - Introduction to the test case and physical phenomena, practical importance and parameters of interest for the UFR
• Test Case - Description of test case experiments
• Evaluation - Comparison of CFD calculations with test case experiments
• Quality Review
• Best Practice Advice
