The following article is from The Great Soviet Encyclopedia (1979). It might be outdated or ideologically biased.

Similarity Criteria

 

the necessary conditions for physical similarity of two phenomena—for example, phenomena experienced by an actual object and by a model of it. Similarity criteria consist in the equality of certain dimensionless quantities, called the characteristic numbers, for the phenomena in question. The numbers themselves are sometimes called the similarity criteria. Among them are the Mach, Reynolds, Prandtl, Strouhal, Euler, and Froude numbers.
