Template:Demo AC Test Over

Provide an overview of the scope of the tests and the experimental approach used. This should cover the main aspects of the experimental set up and the measurement techniques used (LDV, hot wire, pressure tappings etc).

If a scaled model was used, due consideration should be given to model scaling issues. Any model simplifications/idealisations of the AC geometry should also be described (e.g. 2D instead of 3D, omission of detailed features, simplification of complex features, i.e. porous media, use of roughness elements). If important details of the geometry representation are uncertain then the impact of these uncertainties on the DOAPs should be discussed, including possible ways for managing their effect.

Sampling/averaging times, and their effect on quantities measured and on DOAPs in particular, should also be discussed.

Identify all experimental tests for which data is available. In order to minimise the number of test descriptions, it is suggested that, as far as possible, experimental data from various runs or experimental conditions be grouped together under a single test case, if variations to experimental setup can be clearly defined in terms of:

• the governing non-dimensional parameters (GNDPs defined above in 1.5), or

• problem definition parameters (PDPs), such as wind direction, angle of attack, aspect ratio, source rate etc.

It is left to the discretion of each author to decide the most appropriate way for structuring and summarising the test case results, within the broad framework suggested above.

A summary table for all tests should be included as shown below in Table EXP-A. The variables measured in each test should also be clearly identified, (e.g. UVW, k, concentration, etc). A distinction should be drawn between detailed local data (e.g. p(x,y,z)) and data relating to DOAPs which are likely to be global/summary parameters (e.g. coefficient of lift, CL).

All available detailed data should be stored in separate electronic datafiles (according to guidelines set out by the Knowledge Base team at the University of Surrey). These should be summarised as shown below in Table EXP-B, with links to each of the datafiles.
