Professor Andy Woods was recently invited to write a short “Focus on Fluids” article for the Journal of Fluid Mechanics. The article reviews some of the processes leading to dispersion and mixing in porous media, and discusses recent findings and open questions in the field. The paper is now available online here.
In temperate climates, many buildings need heating in winter and cooling in summer. A significant amount of energy can be saved by storing excess heat during the warmer months, and using it to warm up a building in winter. Similarly, storing the wintertime thermal energy reduces the need for air conditioning during the summer. PhD
Encapsulation is used to deliver materials to specific sites, protect fragile materials from harsh external environments or to delay release of an active compound until a desired time. Mohammed Al Sharabi and professor Alex Routh have been working on an EPSRC-funded project looking at making novel encapsulated materials. The project was joint with the Universities
In a number of natural or industrial settings, such as magmatic intrusions or geothermal power systems, subsurface porous rocks are flooded by fluid of a different density and composition than the original formation fluid. As the invading fluid migrates through the formation and reacts, its density and composition might change. In turn, this may lead
All buildings require ventilation to keep the indoor air fresh and clean. With underfloor air distribution, fresh air is supplied at a low level, while exhaust air is extracted from the top of a room. If the room contains a heat source, then a temperature stratification develops and occupants are surrounded by fresh air in
Renewable energy sources such as wind and solar are intermittent, and this leads to the need for substantial energy storage. At times of excessive generation, some of the renewable energy might be converted into hydrogen and stored underground. The hydrogen will then be recovered and used when the renewable sources produce insufficient energy. A recent
