Meeting 2014 TMS Annual Meeting & Exhibition
Symposium Celebrating the Megascale: An EPD Symposium in Honor of David G.C.Robertson
Presentation Title Computational Modelling of Metallurgical Processes: Achievements and Challenges
Author(s) Mark Cross, Nick Croft, Diane McBride
On-Site Speaker (Planned) Mark Cross
Abstract Scope Extractive metallurgical processes rate as amongst the most complex from the perspective of computational modelling. They typically involve multi-phase and multi-component fluid flow in very complex geometries, heat transfer driven by a number of interacting phenomena, solid-liquid-gaseous phase change and so mass transfer together with complex thermodynamics and associated chemical reactions. Beyond the model building itself, key challenges have always involved being able to identify the phenomena present together with their interactions to characterise processes and also experimental laboratory and plant data to parameterise the arising models – it is in this milieu, which require considerable process understanding and subtlety of thought, that David Robertson has made his contributions. We will review the achievements made over the last couple of decades in the computational modelling of extractive metallurgical processes and address some of the remaining challenges to enable simulation based process design as we move through the 21st century.
