A numerical method to compute solidification and melting processes

This paper deals with thermodynamically consistent numerical predictions of solidification and melting processes of pure materials using moving grids. Till date, enthalpy-porosity-based formulations of numerical codes have been generally the popular choice, although because of an artificial numerical smearing of the interface, it is virtually impossible to reproduce a sharp melting/solidificati...

Lattice Boltzmann Modeling for Melting/Solidification Processes

The phenomena of melting and solidification are associated with many practical applications, such as metal processing, castings, environmental engineering, thermal energy storage system in space station and many more. In these processes, matter is subject to a change of phase and consequently, a boundary separating two different phases evolves and moves within the matter. Mathematical modeling ...

Melting Processes and Solidification in Alloys 7 18-625

The present state of melting techniques for IN7 18 and IN625 has well-defined limitations both in terms of the ingot structure and maximum ingot size which is fabricable by the various processes. Although there are methods already in industrial use which would extend both of these limits, since the alloys must be produced at a relatively low cost here are further limitations on the practical ma...

A Multiscale Numerical Method to compute Corona Discharges and Application to Plasma Flow Control Problem

This paper deals with the numerical modelling of corona discharges induced by electrohydrodynamic actuators. A specific numerical method is proposed and discussed to compute the multiscale nature observed in the modelling of corona discharges. The idea consists in a domain decomposition of the computational domain where each subdomain is described with a specific modelling well adapted to the p...
