Structure and Operation 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 Challengess, Underlying Flow Regimes (both described below)and 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. 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
Application Areas are categories of articles of specific interest to a particular sector such as:
- External Aerodynamics
- Combustion
- Chemical, Process, Thermal and Nuclear Safety
- Civil Construction and Heating Ventilation Air Conditioning and Ventilation
- Environmental Flow
- Turbomachinery Internal Flow
These categories are also accessible from the navigation menu bar on the left hand side of the window.
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
- Description
- Test Data
- CFD Simulation
- 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.
Underlying Flow Regimes include:
These categories are also accessible from the navigation menu bar on the left hand side of the window.
The content of each Underlying Flow Regimes (UFR) test case within the Knowledge Base consists of an:
- Abstract
- Description
- Test Case
- Evaluation
- Quality Review
- Best Practice Advice
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 link.

How to Contribute Articles and Provide Feedback
Users are encouraged to comment on, exchange views and opinion on the Silver content in the User Feedback Page. For this they must register by clicking on "Create an account" at the top of any page. By doing this you automatically agree to the terms and conditions given in the Terms and Conditions Page.
Users will not be able to directly edit or change a Silver document, but they are highly encouraged to provide new content, either by suggesting modifications/extensions to existing content or indeed by adding new contributions. In order to do this the user must gain access to the Library by emailing the ERCOFTAC Editorial Board with a request (ERCOFTAC Editorial Board).
