Velocity Concentrations in Stratified Fluids

Journal of the Hydraulics Division, 1962
Examples of velocity concentrations or jets in fluid systems; systems are discussed in which vorticity is present or is generated by density variations; typical jet streams of atmosphere are those related to Gulf Stream and Equatorial Undercurrent; similar phenomena were created in laboratory by using rotating and heated fluids to simulate large scale ...

Accurate tangential velocities for solid fluid coupling

Proceedings of the 2009 ACM SIGGRAPH/Eurographics Symposium on Computer Animation, 2009
We propose a novel method for obtaining more accurate tangential velocities for solid fluid coupling. Our method works for both rigid and deformable objects as well as both volumetric objects and thin shells. The fluid can be either one phase such as smoke or two phase such as water with a free surface.

Nonlinear estimation of fluid flow velocity fields

IEEE Conference on Decision and Control and European Control Conference, 2011
A proper orthogonal decomposition (POD)-based nonlinear estimator for fluid flow velocity fields is developed, which is capable of achieving finite-time convergence of the Galerkin coefficient estimates. Using Galerkin projection and POD-based model reduction, the incompressible Navier-Stokes equations are recast as a set of nonlinear ordinary ...

Molecular theory of barycentric velocity: Monatomic fluids

The Journal of Chemical Physics, 2008
The notion of barycentric velocity appears in irreversible thermodynamics and fluid mechanics, in which it is a field variable obeying the hydrodynamic equations or, more specifically, the momentum balance equation, which is coupled to the rest of hydrodynamic equations.

Hydromagnetic Reflection and Refraction at a Fluid Velocity Discontinuity

The Physics of Fluids, 1963
The problem of hydromagnetic reflection and refraction at a fluid velocity discontinuity is solved. Expressions for the propagation vector of the refracted wave and for the reflection coefficient are derived. It is found that the reflected and refracted waves are pure characteristic waves if the incident wave is a pure characteristic wave.

Bi-velocity hydrodynamics: Single-component fluids

International Journal of Engineering Science, 2009
Abstract Acceptance of the Navier–Stokes–Fourier (NSF) equations as the fundamental equations of single-component continuum fluid mechanics for liquids and gases is noted to be inseparably linked to Euler’s implicit, but unproved, hypothesis that but a single-velocity field is required to characterize the four physically different, context-specific ...

Flow characteristics in horizontal pneumatic conveyance at low fluid velocities–2: solid particle velocity and the velocity ratio of particles to fluid

Advanced Powder Technology, 1993
Abstract In this paper a basic equation for the velocity ratio of particles to fluid was derived on the basis of the observation of solid flow patterns given in a previous report on an established flow at low fluid velocities in horizontal pipes. Measurements of the solid particle velocity for the flow were also conducted by measuring the impulsive ...
