Prof. Andy Woods
Head of Institute
Andy Woods’ research involves developing quantitative models and analogue laboratory experiments to explore some of the challenges associated with fluid mechanics in a range of environmental and energy processes. This includes research on the long-term storage of energy in the geosphere through storage of heat or hydrogen; long-term removal of carbon dioxide from man’s environment through geological storage of carbon in deep saline aquifers; and the development of models to identify novel approaches to reduce energy consumption in buildings through more efficient supply of heat, coupled with the use of thermal batteries for interseasonal heat storage. He also has ongoing research projects exploring the dynamics of volcanic systems and the dynamics of turbulent plumes in both the atmosphere and ocean, with important implications to ocean plastics and deep-sea mining.
Much the research that Andy leads is closely coupled with direct applications in industry or environmental engineering, where idealised models of complex multiphase processes provide a powerful compliment to detailed engineering simulations.
