Structure of the Knowledge Base
Introduction to the QNET Knowledge Base
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. The Gold Domain is restricted to ERCOFTAC members who will be issued with privileged access. However, the list of all Application (AC) Challenges and Underlying Flow Regimes (UFR), (both described below) with their abstracts are in the public domain.
The Silver Domain is the repository for less mature content which is still under discussion and open for improvement. 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 Silver and Silver are fully in the public domain.
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
- Underlying Flow Regimes
The application area section contains 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.
These are generic, well studied test cases capturing important elements of the key flow physics encountered across the Application Areas.
Content of the Knowledge Base
The content of each Application Challenge (AC) test case and Underlying Flow Regimes (UFR) test case article within the Knowledge Base consists of an:
- Abstract - Summary of content
- Description - Introduction to test case and physical phenomena involved, (for ACs also practical importance and parameters of interest and for UFRs, review of previews studies).
- Test Case Studies - Description of test case experiments and CFD simulations (and provision of data and CFD results for ACs)
- Evaluation - Comparison of CFD calculations with test case experiments
- Best Practice Advice
- Quality Review
Please note that only Gold AC and UFR test cases include a quality review form. For more information on quality reviews please click on the following link, Quality Review Documents.
