Simulation of macrosegregation benchmark on a non-uniform computational node arrangement with a meshless method
(2017)
Text en actes de congrés
Accés obertAn application of a meshless numerical method on a macrosegregation benchmark case is developed in the present paper. The test case is solidification in 2D rectangular cavity, filled with liquid metal and chilled from both ... -
The influence of thermal barriers in anisotropic media applied to PCB using MEC
(2017)
Text en actes de congrés
Accés obertMany electronical components were developed during the last years and many efforts were devoted to the miniaturization of their components due to the global tendency. The matrix in which the components are mounted are made ... -
Numerical stability of a fixed point iterative method to determine patterns of turbulent flow in a rectangular cavity with different aspect ratios
(2017)
Text en actes de congrés
Accés obert2D isothermal viscous incompressible flows are presented from the Navier- Stokes equations in the Stream function-vorticity formulation and in the velocity-vorticity formulation. The simulation is made using a numerical ... -
Numerical stability of explicit and implicit co-simulation methods
(2017)
Text en actes de congrés
Accés obertWithin a co-simulation approach, the subsystems are integrated by specific solvers; data exchange is accomplished only at certain user-defined macro-time points. Due to the approximation of the coupling variables by ... -
Numerical simulations of micro jets produced with a double flow focusing nozzle
(2017)
Text en actes de congrés
Accés obertStable and reliable micro jets are important for many applications. Double flow focused micro jets are a novelty with an important advantage of significantly reduced sample consumption. Numerical simulations of double flow ... -
Numerical simulation of shock-tube piston problems with adaptive, anisotropic meshes
(2017)
Text en actes de congrés
Accés obertAbstract. Numerical simulations of the flow generated inside a shock-tube by the motion of a magnetically- driven piston are carried out using a novel finite volume adaptive scheme for dynamic meshes. ... -
Mixed variational formulations for multi-field problems
(2017)
Text en actes de congrés
Accés obertGeneral thermoelastic material models have been investigated over the past decades, see e.g. Reese and Govindjee [1], Holzapfel and Simo [2] and Miehe [3] among many oth- ers. In this paper we present a novel computational ... -
Comparative analysis of a transient heat flow and thermal stresses by analytical and numerical methods
(2017)
Text en actes de congrés
Accés obertThe study of heat flow problems is of extreme importance in engineering, there is a need to know the temperatures imposed and generated, when appropriate, in the structural parts to be able to evaluate the stresses that ... -
A coupled discrete-element model of fluid-saturated rock and the results of studying of the impact of a fluid on the shear strength of a rock under combined compression and shear
(2017)
Text en actes de congrés
Accés obertWithin a discrete-element model of a porous permeable elastic-plastic rock, filled with a fluid, we have studied the shear strength of a fractured interface zone (a shear band) between blocks of a geological medium subject ... -
Stress concentration in ultra-thin coating with undulated surface profile
(2017)
Text en actes de congrés
Accés obertThe uniaxial loading of an isotropic film-substrate system with a sinusoidal surface profile and planar interface is considered under plain strain conditions. We for- mulate the corresponding boundary value problem ... -
Phase-field modelling of ternary eutetic solidification in hot dip galvanization
(2017)
Text en actes de congrés
Accés obertContinuous hot dip galvanizing is one of the commercially most important process techniques used for protecting steel sheets against corrosion. Preheated steel sheets are con-tinuously drawn through a pot with a molten ... -
Monitoring and lifetime prediction of pvc cables: methodology by multiscale and multidisciplinary approach
(2017)
Text en actes de congrés
Accés obertMonitoring of the PVC cables as well as the prediction of their residual lifetime are important issues for the maintenance of the French nuclear power plants (NPPs). To date, the unanimously end of life criterion ...
