It might be thought that the Buckingham technique of finding dimensionless groups would be less powerful than one that produces the full relation. In fact this is not really the case. Dimensionless groups are enormously useful in fluid dynamics, because of the idea of dynamic similarity. camp township ia

As a general example of how dimensionless numbers arise in fluid mechanics, the classical numbers in transport phenomena of mass, momentum, and energy are principally analyzed by the ratio of effective diffusivities in each transport mechanism. The six dimensionless numbers give the relative strengths of the different phenomena of inertia ...

Web2. Self-similarity is not just a 'big deal' in fluid mechanics but in any type of dynamic system in which quantities exhibit similar profiles in time or space. Imagine we look at the case of transient Couette flow where initially the fluid is stationary and the top wall starts moving with speed U.
