Professor Mike AdamsFREng
He is a Fellow of the Royal Academy of Engineering and is Professor of Product Engineering and Manufacture (2004-present) in the School of Chemical Engineering at the University of Birmingham. Previously he was a Senior Scientist with Unilever R&D where he had responsibilities for materials science and product processing. He was awarded the Donald JuliusGroenPrize (1999) and a Silver Medal (2016) by the Institution of Mechanical Engineers, and also a special award at the 6th International Granulation Workshop (Sheffield 2013) for outstanding achievements intribologyand agglomeration science respectively. He has published over 200 scientific papers (h-index 40, 6141 citations) and co-edited four books ontribologyand the dynamics of complex fluids. He is a member of advisory/editorial boards for 5 international journals and has given many invited lectures at international conferences including the Lesley J Ford Lecture (IChemE) in recognition of his contributions to particle technology. He has coordinated a number of large research projects including three by funded the EU c. €13M. His major research interests are process engineering, numericalmodelling,tribology, materials science, adhesion science, diffusion, particle technology, solid-solid interactions (contact mechanics and liquid junctions), nanotechnology, sensory perception,rheologyof complex fluids, colloid and interface science.
Friction and lubrication are studied as part of the field oftribology, which also includes wear and adhesion. Friction is vital in our everyday lives from walking to the precision manipulation of objects to our sense of touch, and critical parts of our bodies depend on reliable lubrication, such as our eye lids and joints. An understanding oftribologyis important in many manufacturing, processing and medical applications. A knowledge of friction and lubrication is essential to specify the stress boundary conditions in continuum computer simulations of processes and product usage foroptimisingequipment design and operation, and also virtual prototyping. It is also required for the interactions laws employed in discrete particlemodellingfor processes in which the feed is in a powder form. In the medical sector, skin friction is a major contributor to pressure sores and lubrication is critical in a wide range of medical devices such contact lenses and catheters. Lubrication governs the efficiency and lifetime of energy generation equipment, e.g. wind turbines and automobile engines. Examples in technology areas include the effective lubrication of MEMS devices and modulating finger pad friction to providehapticfeedback fortouchscreens. The presentation will include a brief history oftribology,focussingon key advances, a description of the mechanisms of friction and lubrication and, finally, applications to skintribology,touchscreenswithhapticfeedback andmodellingwet granular matter as examples of complex systems.
