This talk will discuss the impact of thermal behaviour on a number of geoenvironmental engineering problems ranging from the high temperatures found in geological high level nuclear waste disposal facilities to the low temperatures found in regions of permafrost. A wide range of coupled processes will be considered including convection shrinkage/swelling phase change the movement of moisture due to gradients of vapour pressure matrix suction and cryogenic suctions and also the development of ice lenses. The talk will focus mainly on the development of coupled thermo-hydro-chemical-mechanical (THCM) theoretical and numerical models and their application to geoenvironmental problems. Results from experimental studies looking at moisture movement under thermal gradients and the development of ice segregation will also be presented.
Bio: Dr Cleall graduated from Cardiff University in 1994 with a first class honours degree in Civil Engineering. He remained in Cardiff to read for a PhD which he completed in 1998. His PhD focused on modelling the thermal-hydraulic-mechanical behaviour of expansive clays. Following a period as a researcher at the Geoenvironmental Research Centre he was appointed as an academic member of staff in 2002 in the Cardiff School of Engineering. He has just completed a 12 month secondment to the international consultancy Jacobs where he worked in the sustainable solutions area of the business. He also currently serves on the Geotechnique Advisory Panel and will be on the Advisory Panel for the forthcoming Symposium in Print. Dr Cleall’s research activities initially focused on coupled flow and deformation behaviour in soils and have developed to encompass a number of areas in the subject of geoenvironmental and geotechnical engineering. He has been actively involved in a number of international research programmes (for example the Prototype Repository project and the Integrated Project NF-Pro both key European Commission funded research activities in the area of geological disposal of high level nuclear waste). He has expertise in numerical and analytical modelling saturated and unsaturated soil behaviour pollutant movement in the subsurface behaviour of freezing and thawing soils thermal ground energy and subsurface gas generation flow and management.
