Prof Mahesh Tirumkudulu from the Indian Institute of Technology in Bombay has developed a unique method to measure the viscosity of a drop of liquid based on the fluid mechanics of thin films. A drop of liquid is spread over a substrate by contacting a blade with the drop and moving the blade across the
Large lakes tend to be thermally stratified, with a layer of relatively warm water near the surface, and a deeper layer of colder water underneath. The temperature of the surface water fluctuates over the year, while the temperature of the deeper water remains more stable: hence, the thermal stratification is strongest during the summer, when
During the second part of today’s seminar, MPhil student James Sear presented the results of his new experiments on turbulent plumes in a cross-flow. During the last few months, James has been studying what happens when a steady flux of contaminants are released into a river: the contaminants are transported by the current, while being
During the first part of today’s seminar, PhD student Ross Shepherd presented some of his recent work on the injection and storage of CO2 into underground aquifers. Carbon capture and storage will be required as one of many technologies in the global energy transition, and Ross has been studying how to optimise the injection of
Professor Ljiljana Fruk has been studying the design principles and biomedical applications of organic and hybrid nanomaterials. These can be used for real-time detection of senescent cells in the body. Large concentrations of senescent cells in an organ might be a precursor to cancer, and so detecting these cells in the body might help early
The coastal ocean is a highly dynamic and vital biogeochemical mediator between land and sea. Coastal waters frequently experience poor water quality: this is partly due to submarine groundwater discharges, in which polluted water is released at the bottom of the ocean. These discharges are relatively poorly understood, and research is ongoing to characterise them.
During the first seminar of Easter term, PhD student Dan Toy presented his recent work on building ventilation. Over the last few years, Dan has been studying how the temperature profile in a room with displacement ventilation evolves when the ventilation rate is increased. He ran laboratory experiments, which showed that a layer of hot
Today was the last seminar of Lent term, and Part III student James Fidler presented his recent work on new catalyst materials for hydrogen production through electrolysis. Nobel metals are very expensive, and so research is ongoing to find affordable alternatives for catalyst production. Under the supervision of professor Clarke, James has been investigating the
Professor Matthew Jackson from Imperial College London visited us today and presented his recent work on Aquifer Thermal Energy Storage (ATES) systems. This underground thermal energy storage technology provides large capacity, low carbon heating and cooling to the built environment. Heating and cooling of buildings currently produces 23% of the UK’s greenhouse gas emissions, and
To celebrate his recent submission, PhD student Sam Clarke presented some of the results of his work at the weekly seminar today. During his time at the Institute, Sam has been working on reactive flows through porous rocks, with particular interest in the flows which develop around nuclear waste disposal sites. Nuclear waste items need
