Computational modelling of industrial operations involving multi-physics and multi-scale processes
||By Professor Mark Cross
Industrial operations in materials and metals processing frequently involve
interactions amongst a range of physical phenomena. Sometimes these
phenomen might be very distinctive ( e.g. fluids interacting with structures) and in
others they might involve similar phenomena (e.g. thermal fluid flow)
but over a range of length and time scales.
The modelling of these multi-physics and multi-scale phenomena always
occur in complex geometries in real industrial problems. As such, their
solution requires sophisticated computational procedures embedded within
appropriate software technologies.
Because of the heavy compute challenges
associated with these kinds of simulation then ideally one would want to
use of high performance parallel computer systems in generating solutions
within practical time frames.
This presentation will discuss the challenges of multi-physics and
modelling of industrial problems. In so doing a description of one
computational modelling approach will be outlined and exploited in the
of a range of multi-physics and multi-scale industrial processes, including
granular flows in hoppers, alloy segregation during solidification, metals
extrusion and heap leaching of ores.
