Application Challenge AC7-01
Description
Introduction
Brief description and overview of the Application Challenge (AC). Enough information for the reader to get a good idea of the fluid engineering issues and type of flow regimes involved, and why this makes a good AC. All available experimental and CFD results should be briefly described (i.e. experimental methods, computational domain and turbulence models used).
Relevance to Industrial Sector
An assessment of the relevance of the AC to the Industrial Sector. In particular, is it a test case by which the competency of CFD for the sector can be judged? An indication of the level at which the AC is understood should also be given (in terms of data/insight available, and overall quality).
Design or Assessment Parameters
The design or assessment parameters (DOAPs), are those which will be used to judge the competency of CFD calculations. These must be fully defined (e.g. the lift, drag and pitching moment of a wing; the pressure recovery in a diffuser; the species concentration at a given location downstream from a building, etc).
Flow Domain Geometry
The flow geometry associated with the AC should be fully described including clear diagrams or illustrations (preferably, the geometry should also be specified in digital form).
This description should include
- geometrical features of the domain and their dimensions, locations of all boundaries
- conventions (e.g. coordinate system used, sign conventions etc)
Flow Physics and Fluid Dynamics Data
The key aspects of the flow physics (e.g. laminar/turbulent,
compressible/incompressible, heat transfer/isothermal, etc) and the
governing non-dimensional parameters (GNDPs) (e.g Reynolds, Mach,
Grashof numbers, etc.) should be identified clearly. The physics of
other key processes (such as chemical kinetics, flow through porous
media, etc) must also be discussed. All the fluid dynamics data (except
boundary conditions) which are necessary in order to set up a CFD
simulation must be described. The properties of the working fluid(s)
must be specified or readily deducible (e.g a statement that it is air
is sufficient, however if the fluid is non-newtonian, the appropriate
constitutive law(s) must be given).
