Wikipedia:Articles for deletion/Non-dimensionalization and Scaling of Navier-Stokes Equation
To my opinion, this is just as undesirable as Non-dimensionalization and scaling of Newton's second law (note that the Navier-Stokes equations are just the application of Newton's second law to a Newtonian fluid in continuum mechanics). As long as you do not know the case on/for which the non-dimensionalization and scaling is to be applied, it is meaningless. The questions one has when making/using some model to a certain problem are: which simplifications are allowable, which approximations still lead to results of a desired accuracy? Are gravity, electromagnetic forces, quantum or relativistic effects important? Can I use the continuum hypothesis, or can a body be considered rigid, or even as a point mass? Are relativistic gravity effects important, or can I use Newton's law of gravity? Those questions are associated with different meaningful (skillful) non-dimensionalizations of each problem. Where it is crucial that the important (and problem-specific) characteristic values of the key problem parameters/fields are quantified. So the vast diversity of different (types of) problems leads to a sheer countless number of different meaningful non-dimensionalizations (and associated simplified model equations or scale models), which cannot be covered in such an article. It will result in a |textbook or |HowTo, which are the aim of projects like Wikiversity but not of Wikipedia
