A Subgrid Viscosity Lagrange-galerkin Method for Convection-diffusion Problems

Abstract. We present and analyze a subgrid viscosity Lagrange-Galerkin method that combines the subgrid eddy viscosity method proposed in W. Layton, A connection between subgrid scale eddy viscosity and mixed methods. Appl. Math. Comp., 133: 147-157, 2002, and a conventional Lagrange-Galerkin method in the framework of P1⊕ cubic bubble finite elements. This results in an efficient and easy to i...

The Permeability of Capillaries in Various Organs as Determined by Use of the 'indicator Diffusion' Method.

CRONE, C. The permeability of capillaries in various organs as determined by use of the ‘Indicator Dzffusion’ method. Acta physiol. scand. 1963. 58. 292-305. The theory of a single injection technique, the ‘Indicator Diffusion’ method, for quantitative studies of capillary permeability is developed. It is shown that the permeability of a capillary area can be expressed by three parameters: the ...

Diffusion of nitrogen in R2Fe17 (R =rare earth) compounds determined by the Kissinger method

The activation energy of nitrogen diffusion in R2Fe,, (R=rare earth) compounds has been determined by applying the Kissinger method to analyse the differential scanning calorimetry (DSC) traces of nitrogenated R2Fe1, compounds. The nitrogen outgas that starts when the nitrides are heated above about 300 “C is a typical decomposition reaction of the type solid + solid + gas to which the Kissinge...
