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.

-'''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:Intro#|Library]] by emailing the ERCOFTAC Editorial Board with a request ([mailto:rodi@ifh.uni-karlsruhe.de ERCOFTAC Editorial Board]). The email must set out;
-* The title of the test case considered
+[[AC_Index#|AC Index]]
-* 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.
