Isentropic correction for collocated Lagrange-Remap scheme

A low diffusive Lagrange-remap scheme for the simulation of violent air-water free-surface flows

In 2002, Després and Lagoutière [Després and Lagoutière (2002)] proposed a low-diffusive advection scheme for pure transport equation problems, which is particularly accurate for step-shaped solutions, and thus suited for interface tracking procedure by a color function. This has been extended by Kokh and Lagoutière [Kokh and Lagoutière (2010)] in the context of compressible multifluid flows us...

An Anti-diffusive Lagrange-remap Scheme for Multi-material Compressible Flows with an Arbitrary Number of Components

We propose a method dedicated to the simulation of interface flows involving an arbitrary number m of compressible components. Our task is two-fold: we first introduce a m-component flow model that generalizes the two-material five-equation model of [2,3]. Then, we present a discretization strategy by means of a Lagrange-Remap [8,10] approach following the lines of [5,7,12]. The projection step...

REMAP for video soundtrack indexing

Indexing of video soundtracks is an important issue for the navigation in multimedia databases. Based on wordspotting techniques, it should meet very constraining specifications; namely fast response to queries, concise processed speech information for limiting the storage memory, speaker independant mode, easy characterization of any word by its phonemic spelling. A solution based on phonemic ...

A high resolution scheme for Eulerian gas-solid two-phase isentropic flow

Numerical solutions of the equations governing two-phase isentropic flow of a solid granular material dispersed in a gas are investigated. Both the dispersed and continuous phases are treated as continua and an Eulerian description of the flow is adopted. We present an inviscid model with a general pressure term from which a number of variant models can be obtained. A high resolution scheme is ...
