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 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. Some examples of these include:

• External Aerodynamics
• Combustion
• Chemical, Process, Thermal and Nuclear Safety
• Civil Construction and Heating Ventilation Air Conditioning and Ventilation
• Environmental Flow
• Turbomachinery Internal Flow

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

These categories are also accessible from the navigation menu bar on the left hand side of the window.

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:

• Free flows
• Semi-Confined Flows
• Flows Around Bodies
• Confined Flows

These categories are also accessible from the navigation menu bar on the left hand side of the window.

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). The email must set out;

• The title of the test case considered
• The list of authors
• Is the test case considered in the AC or UFR category?
• Is it a new AC or UFR or a modification of an existing one?
• Abstract describing briefly the contents of the new AC or UFR or which parts of an existing one are modified or extended

The ERCOFTAC Editorial Board will respond with an email that either approves or declines the request. If successful, the response will give a username and password enabling access to the Library Area together with instructions on where to find the article template assigned to you. Enter the Library Area, access the article template and begin to make your contribution. When this is completed, inform the Editorial Board by sending a short email giving your name and article or test case title. The editor will review the article and if and when it meets his requirements it will be lifted into the Silver Domain either as a new document or replacing the existing one.
