In fluid mechanics, non-dimensionalization of the Navier–Stokes equations is the conversion of the Navier–Stokes equation to a nondimensional form. Need for non... · Stokes regime · References |
For incompressible flow, Equation 10-2 is dimensional, and each variable or property (ρ, V , t, μ, etc.) is also dimensional. |
In fluid dynamics, the dimensionless Navier-Stokes equation is the main tool used to generalize fluid flow behavior into new domains and systems. |
