The dynamics of isocirculational flows
Geophysical & Astrophysical Fluid Dynamics, 1985Abstract Barotropic flows are described in terms of mass preserving velocity fields of the vortex lines and non-barotropic flows by mass preserving velocity fields that move with the entropy and the potential vorticity. In these representations, all locally conserved quantities of inviscid flows are a priori given functions of the positions of the ...

Dynamics of Glacier Flow [PDF]
, 2009 As mentioned in the introduction (Chapter 1), the size of land ice masses spans several orders of magnitude, from large ice sheets of a few thousand kilometres in diameter down to small glaciers of a few hundreds of metres in length. Consequently, the scaling given for ice sheets in Chapter 5 [Eqs.

The principles that govern fluid motion in normal blood vessels can still be best approached by using the classic Poiseuille model. This law states that the ratio of the pressure gradient (PI - P2) to flow (Q) is a function of the tube dimensions and the viscosity (μ) of the moving fluid: $$\frac{{P1 - P2}} {Q} = \frac{{8\mu L}} {{\pi (r^4 )}} $$

In 1951, Loebenstein and Deitz [1] described an innovative gas adsorption technique that did not require the use of a vacuum. They adsorbed nitrogen out of a mixture of nitrogen and helium that was passed back and forth over the sample between two burettes by raising and lowering attached mercury columns.

Abstract A dynamic flow birefringence theory is proposed for macromolecular solutions of arbitrary structure. Hydrodynamic interaction between macromolecular elements was examined by the Oseen method. It was shown that the dynamo-optical constant [n] is determined by the mechanical (via the rotary diffusion constant) and optical properties of the ...

Ausgehend von der Tatsache, dass eine Schaufelreihe aquivalent ist einem Kraft- und damit auch einem Wirbelfeld, wird der Begriff der Potential-Kraft-Stromung erweitert. Diese schliesst den «von Mises-Fall» ein, wenn das Euler-Integral im ganzen Feld konstant ist.

Extensive lava flows, like those of the Columbia plateau of Washington state, require thicknesses only of the order of meters and temperatures only slightly above the melting point to spread over distances of the order of hundreds of kilometers. Other things being equal, the spreading distance is proportional to the cube of the thickness of the flow.

Problems of the flow of complex suspensions or melt materials and powders are classified according to the existence of exact formulations and of useful models. Regimes of interest are classified into dilute, entangled, and packed, and the difficulties and sucesses of the different types of objects and the different types of regimes are studied ...

Transport models in the preceding chapters focused on contaminant, or solute, transport. We derived basic conservation laws that governed how the solutes were advected and dispersed throughout the medium, and we imposed relations that governed the kinetics of adsorption of those solutes. The subject of contaminant transport is just one aspect of porous
