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).
