Heuristic and Eulerian interface capturing approaches for shallow water type flow and application to granular flows

Multifluid Flows, Interface Capturing and Application to the Simulation of the Water Assisted Injection Molding Process

In this paper, we present a 3D finite element approach to compute multifluid flows. Special attention is given to capture the water/polymer interface, that can be obtained used a VOF (Volume of Fluid) or a Level Set technique, with or without adaptative meshing. Results are shown, in for 2D and 3D parts.

A Level Set Formulation of Eulerian Interface Capturing Methods for Incompressible Fluid Flows

the front and avoid introducing numerical diffusion which smooths out the front. In the case of irrotational flow, one A level set formulation is derived for incompressible, immiscible Navier–Stokes equations separated by a free surface. The interface can reformulate the problem in the boundary integral form is identified as the zero level set of a smooth function. Eulerian so that it involves ...

construction and validation of translation metacognitive strategy questionnaire and its application to translation quality

like any other learning activity, translation is a problem solving activity which involves executing parallel cognitive processes. the ability to think about these higher processes, plan, organize, monitor and evaluate the most influential executive cognitive processes is what flavell (1975) called “metacognition” which encompasses raising awareness of mental processes as well as using effectiv...

Nonclassical Shallow Water Flows

This paper deals with violent discontinuities in shallow water flows with large Froude number F . On a horizontal base, the paradigm problem is that of the impact of two fluid layers in situations where the flow can be modelled as two smooth regions joined by a singularity in the flow field. Within the framework of shallow water theory we show that, over a certain timescale, this discontinuity ...
