The Longyou Caves represent an important historical site in China that has undergone periodic water level changes over several centuries. The ground water flow through the intact rock and fractures is an important factor in the geotechnical assessment of the site. The Environmental Geomechanics Laboratory at McGill University has focused on the development of innovative theoretical approaches and experimental facilities for wide range of rocks including Indiana Limestone, the Cobourg Limestone, the Vermont Granite and the Lac du Bonnet Granite, using both steady state and transient techniques. In this Teck Talk, Professor Selvadurai will present a range of experimental techniques, their theoretical interpretations that can be used to estimate of fluid transport processes through intact rocks that can be described by Darcy’s law. The theoretical and experimental techniques are used to determine the intact permeability of Longyou claystone recovered from the site.
Professor APS Selvadurai obtained his PhD and DSc degrees in Theoretical Mechanics from the University of Nottingham, under the tutelage of the late Professor AJM Spencer FRS. He conducts research and has extensively published in the areas of applied mathematics and mechanics, multi-physics problems in geoenvironmental engineering and experimental mechanics. He has published extensively in these areas and received numerous awards including the Humboldt Senior Scientist Award, the Max Planck Prize, Killam Prize, the Booker Medal, The IACMAG Medal, The Desai Medal, The Leipholz Medal, The CANCAM Medal, The Biot Medal and the Reissner Medal. He is a Fellow of the Royal Society of Canada, The Canadian Academy of Engineering, The American Academy of Mechanics, The Canadian Society for Civil Engineering, the Engineering Institute of Canada and the Institute of Mathematics and its Applications, UK.
Clean water and clean air are vital for public health. This project focuses on developing high-efficiency and environmentally sustainable filters for removing harmful air/water pollutants. The team has developed novel architectures and functionalities for the filters to achieve high permeance, high removal efficiency, and excellent reusability.
