Using advanced computational simulation and image processing technology to understand
Developing advanced image analysis for the characterization of materials including particles, porous materials and composites.
Providing better visualization, automatic measurements of a range of morphological and topological properties, texture classification, object detection and classification.
Recomposing of 3D nano-structures by 3D tomography. The material can be virtually recomposed into ultra-thin slices in order to access its properties.
Nanofluidics are a new class of fluids which consist of a base fluid with suspended nano-sized particles (1-100 nm). The particles are generally metals or oxides, increasing heat transfer (conduction and convection) coefficients.
Nanotechnology is being used or considered for use in many applications to provide cleaner, more efficient energy supplies and uses. These include engine cooling, engine transmission oil, cooling of electronics, boiler exhaust flue gas recovery, heating and cooling of buildings, domestic refrigerator and chiller cooling, nuclear systems cooling, solar water heating, defence, space and biomedical applications, lubrications, thermal storage and drag reductions.

A fluidized bed allows fine solid particles to behave like a liquid by the flow of supporting gas from the bottom of the solid bed.
Various heat and thermo-chemical treatment processes can be performed in a fluidized bed by modifying parameters such as temperature, gas mixture and solid/gas mixture. The advantages of a heat treatment fluidized bed are near ideal temperature uniformity through the whole gas-particle volume and rapid heating of the parts treated.
Thermo-chemical heat treatment is a complex diffusion process of metallic and non-metallic elements (such as C, N and Cr) into a thin substrate surface to modify the surface chemistry and microstructure of components. It includes gas-solid flow, heat transfer, species transport, chemical reactions of fluidizing gases, decomposition of gaseous molecules, absorption of atoms and diffusion of the elements in metallic components.
The Computational Fluid Dynamics group's mission is to comprehensively improve the understanding of the chemical reactions and mass transfer in fluidizing gases and between the fluidizing gases and immersed metallic parts, as well as the dynamics and heat transfer in fluidized beds, where multiple parts and a basket of parts are immersed.
