Introduction to the Knowledge Base

The test cases are application centred, facilitating the identification of appropriate knowledge and advice for specific industrial purposes. They are organised around:

Application Areas
Underlying Flow Regimes
Direct Numerical Simulations
Experimental Studies

Application Areas (AC)

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, Environmental Flows and Biomedical Flows.

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.

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.

Experimental Studies (EXP)

These are well-studied test cases providing experimental data for gaining insight into the flow physics and for testing CFD methods

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 previous studies).
Test Case Studies - Description of test case experiments and CFD simulations (and provision of data and CFD results for ACs, and also for some UFRs)
Evaluation - Comparison of CFD calculations with test case experiments
Best Practice Advice

The content of each Direct Numerical Simulations (DNS) test case article also consists of an Abstract, Introduction to the physical phenomena, a brief review of previous studies and then:

Test case description with geometry and boundary conditions
Computational details
Quantification of resolution
Results of simulation with discussion

Also the content of each Experimental Studies (EXP) test case consists of an Abstract, Introduction to the physical phenomena, a brief review of previous experimental studies and then:

Test-case description with geometry and flow parameters
Experimental set up
Measurement quantities and techniques
Data Quality and Accuracy of measurements
Measurement data/results

The AC and EXP articles are expected to have, and should contain, links to detailed data files for all experimental and, in case of AC, also CFD results according to the guidelines set out here. In the UFR articles it is sufficient to present the data as plots, although it is highly desirable to provide links to associated databases where these are available. The templates for compiling AC, UFR, EXP and DNS articles can be found in the Template Library. For DNS cases data should be provided for the desirable/minimum quantities listed here according to the data storage guidelines set out here.

+'''Introduction to the Knowledge Base'''
-The knowledge base is partitioned into Gold and Silver Domains. The Gold Domain is the repository for high value content and advice which has been rigorously checked for accuracy and reliability. The Silver Domain is the repository for content which is under discussion and development, as such it is less mature. Parts of the Silver Domain are marked as Silver [[Image:star_red.jpg]]. This is reserved for content which has matured to levels of quality and significance approaching Gold standard.
+<!--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 [http://www.ercoftac.org/ ERCOFTAC] members who will be issued with privileged access. However, the list of all Application Challenges (AC) 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 [[Image:star_red.jpg]]. 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 [[Image:star_red.jpg]] and Silver are fully in the public domain.

-Anyone will be able to comment on, exchange views and opinion on the Silver content, but will not be able to directly edit or change a Silver document. Such material can only be edited by the following procedure set out in the [[Library area]].
-The [[library area]] is where potential contributors can edit existing doucuments or add new content. By following  access all the templates by which they can revise, refine or add new content into a Silver document. It is also possible to create entirely new test case documents. The editor will review all such submissions and subject to his authority/permission, the silver content will be replaced by such submissions or indeed the content will be expanded. Over the course of time, as Silver content becomes refined and improved to the quality and value of the gold standard, it will be transferred into the Gold segment.
