The activities of our group are in the broad area of heat and mass transfer, thermodynamics, and fluid dynamics. Our current focus is on technologies for desalination of seawater and brackish water, and remediation of various waste waters, with increased energy efficiency and reduced environmental impact as core objectives. This work includes thermodynamic cycle analysis, transport processes in components, solar-energy driven systems, and both thermal and membrane separations.
Water scarcity is present worldwide in diverse societies and settings, and the situation is continuing to worsen: our renewable freshwater supply from net precipitation over land is fixed, whereas world population will rise to 9 billion by 2050 from 3 billion in 1960. Further, the world’s population is increasingly an urban population amounting to more than 50% today and on track to reach 64% of the developing world and 86% of the developed world by 2050. The projected impact of global climate change compounds these effects. The provision of water for the world’s diverse populations will require energy-efficient, low-carbon technologies for creating potable water from saline sources (the oceans, in particular) and from impaired water supplies (by recycling of used water). Increased urbanization implies that infrastructure-scale solutions will be essential; but, in addition, the rural developing world faces an urgent need for small-scale, locally-powered water purification systems.
Past activities in our lab have included thermal management of electronics, high heat flux engineering, thermal stress and deformation, thermal manufacturing processes, liquid jet impingement cooling, instrumentation, thermally stratified turbulent flow, and thermally driven instabilities. Descriptions of some of these projects and publications are given in the links on the right.
