Abstract This paper presents a comparison between two numerical methods for modelling the mechanical and failure behaviour of aluminosilicate glass: Cohesive Elements Method (CEM) Finite Element coupled to Smooth Particle Hydrodynamics (FEM-SPH). The behaviours, provided by these approaches, are herein compared under i) quasi-static tests on material coupons, ii) dynamic (compressive tensile te...

We investigate a multidimensional nonisentropic radiation hydrodynamics model. We study the local existence and the convergence of the nonisentropic radiation hydrodynamics equations via the non-relativistic limit. The local existence of smooth solutions to both systems is obtained. For well-prepared initial data, the convergence of the limit is rigorously justified by an analysis of asymptotic...

A brief description of the Smoothed Particle Hydrodynamics method is presented together with some test calculations and astrophysical examples of accretion phenomena.

Hydrodynamics of gas-particle two-phase turbulent flow in a circulating fluidized bed riser is studied experimentally by Particle Image Velocimetry (PIV) and numerically with the use of a 3D discrete hard sphere particle model (DPM). Mean particle velocities and RMS velocities are obtained and the influence of turbulence on the flow is investigated. The experimental data are analyzed and compar...
