Meaning of nondimensionalization | Babel Free

Definitions

The partial or full removal of units from an equation involving physical quantities by a suitable substitution of variables, in order, for example, to simplify and parameterize problems where measured units are involved.

countable, uncountable

“This appendix outlines the role of several key dimensional and nondimensional parameters in micro- and nanoscale fluid mechanics that come from nondimensionalization of governing equations. A key advantage of nondimensionalization is that it leads to a compact description of flow parameters (i.e., Re) and thus leads to generalization. Nondimensionalization can be a powerful tool, but it is useful only if implemented with insight into the physics of the problems.”

“Each computer code will have a set of reference nondimensionalizations similar to these; a specific example is given in Section 3.5.3.”

“We show how our Python interface outperforms the existing text-file-based configuration mechanism, providing features like automatic nondimensionalization of physical quantities and handling of complex parameter dependencies.”
