Conference Objectives:

The conference aims to:

  • Showcase the continuing development in the theory and modeling of phenomena related to solidification including application to casting, welding and related processes.
  • Gather together an international group of experts from academia, industry, government laboratories and software companies who share a common interest in the field of solidification modeling and it application to scientific enquiry and industrial processes.
  • Openly share ideas through formal presentations, posters and one-on-one meetings in an environment conducive to open discussion.
  • Present the latest numerical developments and their applications.

Topics

Phenomena occurring at all length scales during solidification in casting and welding processes are covered by the conference and include, but are not limited to, the following topics:

  • heat transfer (diffusive, advective and radiative)
  • mass transfer (diffusive and advective)
  • fluid flow (single phase, multiphase and free-surface behaviour, newtonian and non-newtonian fluids, buoyancy effects, thermosolutal effects, turbulence, magneto-hydrodynamics, Marangoni)
  • Coupling and multi-physics phenomena (thermal-stress, thermal-fluid, thermal-stress-fluid, electromagnetic)
  • Segregation phenomena (micro, macro, exudation, multi-component, deformation induced)
  • Micro and macrostructure formation (solid-liquid interface development, dendritic, eutectic, peritectic, columnar, equiaxed, kinetics, phase selection, crystallographic orientation)
  • Defect formation (micro-porosity, shrinkage cavities, hot tearing),
  • Thermodynamics (coupling with segregation and structure development),
  • Numerical methods (volume averaging, finite differences, finite volume, finite elements, front tracking,sharp interface, phase field, cellular automaton, deterministic and stochastic, level set),
  • Experimental methods for model validation (in-situ X-Ray imaging, tomography)
  • Measurements for model applications and/or validation (thermophysical and thermomechancial properties, inverse methods, metallography,microscopy, composition, EBSD)
  • Casting Technology (conventional, continuous, remelting, investment, permanent mould, lost foam, sand, near-net shape, welding, joining, rapid solidification processes).
