Abstract In this paper, we present a novel spatial reconstruction scheme, called AENO , that results from special averaging of the ENO polynomial and its closest neighbour, while retaining stencil direction decided by choice. A variant m-AENO, modified (m-ENO) neighbour. The concept is thoroughly assessed for one-dimensional linear advection equation non-linear hyperbolic system, in conjunction...

Numerical methods are developed to simulate the wave propagation in heterogeneous 2D fluid / poroelastic media. Wave propagation is described by the usual acoustics equations (in the fluid medium) and by the low-frequency Biot’s equations (in the porous medium). Interface conditions are introduced to model various hydraulic contacts between the two media: open pores, sealed pores, and imperfect...

In the numerical simulation of three dimensional fluid dynamical equations, the huge computational quantity is a main challenge problem. Based on the three dimensional consistent unstructured tetrahedron meshes, we study the discontinuous Galerkin (DG) finite element method [1] combined with the adaptive mesh refinement (AMR) [2, 3] for solving Euler equations in this paper. That is according t...

A time-domain numerical modeling of Biot poroelastic waves is presented. The viscous dissipation occurring in the pores is described using the dynamic permeability model developed by Johnson-Koplik-Dashen (JKD). Some of the coefficients in the Biot-JKD model are proportional to the square root of the frequency: in the time-domain, these coefficients introduce order 1/2 shifted fractional deriva...

Here we extend the flux vector splitting approach recently proposed in (E F Toro and M E Vázquez-Cendón. Flux splitting schemes for the Euler equations. Computers and Fluids. Vol. 70, Pages 1-12, 2012). The scheme was originally presented for the 1D Euler equations for ideal gases and its extension presented in this paper is threefold: (i) we solve the three-dimensional Euler equations on gener...

This work presents novel compact High Temperature Superconductor (HTS) microstrip resonators based on Hilbert fractal curves. Their miniaturization performance has been investigated, emphasizing the parameters which allow to obtain a good trade off between compact size and quality factor. Hilbert resonators with different arrangements have been designed and assessed by using full wave simulator...

An effective action is obtained for the N = 1, 2D−induced supergravity on a compact super Riemann surface (without boundary) Σ̂ of genus g > 1, as the general solution of the corresponding superconformal Ward identity. This is accomplished by defining a new super integration theory on Σ̂ which includes a new formulation of the super Stokes theorem and residue calculus in the superfield formalism....
