The University of Cambridge BP Institute was established in 2000 by a generous endowment from BP, which has funded faculty positions, support staff and the Institute Building, in perpetuity. The Institute research focuses on fundamental problems in multiphase flow and is highly interdisciplinary, spanning six University Departments.
There is a new fully funded iCASE PhD award to study the fluid dynamics of Carbon Sequestration with Prof Woods in the BP Institute from October 2019 for 3.5 years. Candidates should have a good degree in mathematics, physics, chemical engineering or engineering (1st or 2.1). The project will explore the effectiveness of CO2 injection into heterogeneous reservoirs to gain insight into the possible fraction of the pore space flooded by the CO2 and also to explore the fraction of CO2 which may be extracted from a system following injection.
The UK Fluids Conference aims to bring together all those involved in fluid mechanics research in the UK. PhD students and post-doctoral researchers are encouraged to attend as well as established researchers. There will be a lively programme of invited and contributed talks, and poster sessions, to foster communication amongst the community.
It will be held in Cambridge on 27–29 August 2019 at the Department of Applied Mathematics & Theoretical Physics, and at Churchill College.
The investigation of buried interfaces, such as the mineral/aqueous solution interface, is experimentally challenging. Neutron reflectometry is a well-established and non-invasive technique that allows behaviour at these interfaces to be measured, and a technique has been developed within the group to allow the surface of the mineral muscovite mica to be measured. This surface shows atomic flatness due to perfect cleavage along the basal plane, and is negatively charged in solution.
We show how droplets which comprise two solvents of different volatility can display an instability during drying. This can drive suspended solutes to the edge of the droplets and create a non-homogeneous final film.
We make micron sized water core droplets surrounded by a polymer shell and then place a silver layer around the entire droplet to seal it. The capsules can be used to deliver pharmaceuticals and other small molecules to desired locations.
Buried interfaces, pertinent to realistic environments such as those found in a car engine, are notoriously difficult to investigate due to the challenges of accessing information concerning the interface itself without being swamped by the much greater signal from the bulk materials; here, we describe the combination of a suite of sophisticated surface study techniques to characterise small molecules adsorbing at key metal surfaces from an oil phase.
Understanding the structure and behaviour of proteins adsorbing at key biomaterial surfaces is both challenging but also critical to designing implants that interact favourably with the body. Here, we report the first use of the powerful surface analysis technique neutron reflectometry to characterise a stainless steel surface and the adsorption of key proteins found in the blood plasma thereupon.
Figure illustrating the very thin mica sheet on the silicon block support. The Data shows the distinctive ‘double critical angle’ indicative of the mica/D2O interface (the two ‘steps’ at low Q) and the changes on adsorbing a layer of AOT at the mica surface, clearly evidence at high Q. using data such as this we can identify and structurally characterise the layers at the mica surface.
Migration of CO2 through storage reservoirs can be monitored using time lapse seismic reflection surveys. At the Sleipner Field, injected CO2 is distributed throughout nine layers within the reservoir. These layers are too thin to be seismically resolvable by direct measurement of the separation between reflections from the top and bottom of each layer. Here we develop and apply an inverse method for measuring thickness changes of the shallowest layer.
