The Centre of Numerical Modelling and Process Analysis

About

CSEG is the most diverse of the four research groups within the CNMPA. Its origin coincides with that of the CNMPA, founded by Cross & Markatos in 1986. Since then, the CSEG has worked in a whole range of industrial or environmental problems involving fluid flow, heat transfer, chemical reaction, phase change, stress analysis and even electromagnetics. The group is particularly known for its expertise in metals and minerals processing (smelting, casting, welding, solidification microstructure, etc.) with a long-term involvement in a number of projects of international significance; eg. the modelling of the Rio-Tinto HIsmelt® process in Western Australia for the direct smelting of iron ore into iron, replacing the Blast Furnace technology. Experience in metal processing highlighted the need for "Multi-physics" modelling, which has remained the focus of research. In this context, the CSEG is responsible for the creation of some unique algorithms and software, including the multi-physics code PHYSICA, the spectral code SPHINX used in the joint EU/ESA project IMPRESS, to model strongly coupled Magneto-hydrodynamic problems (induction melting, em. Levitation), the code MHD_VALDIS modelling the aluminium electrolysis process, etc. Other areas of EPSRC, EU or Industrially-funded research cover aero-acoustics, microwaves, particulates handling, atmospheric and water pollution.
