  2. Dimensionless numbers in fluid mechanics - Wikipedia

    en.wikipedia.org/wiki/Dimensionless_numbers_in...

    Dimensionless numbers (or characteristic numbers) have an important role in analyzing the behavior of fluids and their flow as well as in other transport phenomena. [1] They include the Reynolds and the Mach numbers, which describe as ratios the relative magnitude of fluid and physical system characteristics, such as density, viscosity, speed of sound, and flow speed.

  3. Dean number - Wikipedia

    en.wikipedia.org/wiki/Dean_number

    The Dean number (De) is a dimensionless group in fluid mechanics, which occurs in the study of flow in curved pipes and channels.It is named after the British scientist W. R. Dean, who was the first to provide a theoretical solution of the fluid motion through curved pipes for laminar flow by using a perturbation procedure from a Poiseuille flow in a straight pipe to a flow in a pipe with very ...

  5. Rossby number - Wikipedia

    en.wikipedia.org/wiki/Rossby_number

    The Rossby number (Ro), named for Carl-Gustav Arvid Rossby, is a dimensionless number used in describing fluid flow. The Rossby number is the ratio of inertial force to Coriolis force , terms | v ⋅ ∇ v | ∼ U 2 / L {\displaystyle |\mathbf {v} \cdot \nabla \mathbf {v} |\sim U^{2}/L} and Ω × v ∼ U Ω {\displaystyle \Omega \times \mathbf ...

  6. Euler number (physics) - Wikipedia

    en.wikipedia.org/wiki/Euler_number_(physics)

    The Euler number (Eu) is a dimensionless number used in fluid flow calculations. It expresses the relationship between a local pressure drop caused by a restriction and the kinetic energy per volume of the flow, and is used to characterize energy losses in the flow, where a perfect frictionless flow corresponds to an Euler number of 0.

  9. Graetz number - Wikipedia

    en.wikipedia.org/wiki/Graetz_number

    A Graetz number of approximately 1000 or less is the point at which flow would be considered thermally fully developed. [ 2 ] When used in connection with mass transfer the Prandtl number is replaced by the Schmidt number , Sc, which expresses the ratio of the momentum diffusivity to the mass diffusivity.
