Droplets evaporation is fundamental problem which is relevant to a wide range of technological, biological and natural processes. Understanding the fundamentals of this problem is paramount to development of new technologies and advancements. In this talk, we present some of the latest advances in unraveling aspect of droplets wetting and phase change. We will present results concerning, effect of substrates thermal properties, thermocapillary instabilities, complex fluids such as polymers and nanofluids evaporation and lifetimes of droplets. We will also present an applied aspect from this problem related to Leidnefrost effect. The new concept of Leidenfrost engine will be introduced and discussed.
Professor Khellil Sefiane is a Professor of Thermophysical Engineering at the University of Edinburgh in Scotland and Deputy Head of the Research Institute for Materials and Processes (IMP). He is vice president of the UK Heat Transfer Committee. He has been associate editor for the International Journal of Multiphase Flows, Elsevier and the ASME Journal of Heat Transfer. He has a long interest in heat and mass transfer and multiphase flow problems with a focus on both novel experimental techniques and numerical modelling. His studies of evaporating droplets have included identification of self-excited hydrothermal waves, influence of substrate conductivity, adsorption dependence, infrared themography to study contact line dynamics, flow transition within evaporating binary mixtures and suppression of ring stain formation during polymer solution droplet evaporation. In 2009, he received the Institute of Physics Printing & Graphics Science Group Prize for his “Fundamental studies on droplet evaporation”. He holds an ExxonMobil fellowship awarded by the Royal Academy of Engineering (2000), is a Fellow of the Royal Society of Chemistry, a Japan Society for the Promotion of Science Fellow (Kyushu University, Japan, 2011), an elected UK representative on EUROTHERM Com. (http://www.eurothermcommittee.eu), an elected member of the Scientific Council of the Int. Centre for Heat and Mass Transfer (http://www.ichmt.org/). He is corresponding member of the European Academy of Sciences Art and letters. He has published more than 150 refereed journal papers (http://wok.mimas.ac.uk).
