Research carried out in the School of Mathematics at the University of Bristol between 1998 and 2005 has been instrumental in the development of structures that arrest or deflect the rapid flow of snow that characterises avalanches in mountainous regions of the world. The research has been embodied in a series of guidance documents for engineers on the design of such structures and many defence dams and barriers have been built across Europe since 2008. The guidance is now adopted as standard practice in many of the countries that experience avalanches. Investment in avalanche defence projects based on the design principles set out in the guidance runs into tens of millions of pounds. The Bristol research is also used internationally in the training of engineers who specialise in avalanche protection schemes. Given the scale of the threat to life and property from these potent natural hazards, the impact of the research is considerable in terms of the societal and economic benefits derived from the reduction of the risk posed by snow avalanches.
Commercialisation: Through government grants, institutional and private investors, a medical devices company (Vascular Flow Technologies) was founded.
Products: Spiral Laminar Flow™ Vascular Grafts for use in bypass for peripheral arterial disease and vascular access for haemodialysis.
Market / Sales: Spiral Laminar Flow™ Grafts are sold in 18 countries, with over 3000 grafts implanted (<1% estimated market size) and sales in excess of £1million.
Patient Outcomes: Published and presented clinical series show the grafts have increased survival rates leading to reduced re-interventions and reduced amputations.
Cost savings in the order of £130M over the REF period have been achieved by Rolls-Royce through the improvement of engine reliability of civil and military aero-engines, industrial machines used for electricity generation and gas/oil pumping applications through the use of techniques and processes developed by the Vibration University Technology Centre (UTC) at Imperial College London.
University of Huddersfield research into the optimal design of flow-handling systems has been credited with "transforming" the development strategies and global market sales of an industrial partner. Weir Valves and Control Ltd has enjoyed a 75% saving in design lead time and a 1,800% increase in annual sales - from several thousand before its collaboration to millions in 2013 - through the structured integration of researchers' computational fluid dynamics expertise in its design process. The success of this collaboration, which has been described as an exemplar of a Knowledge Transfer Partnership, has also led to further research contracts.
Since the 1970's the influence of aerodynamics on racing car design has risen substantially, and now in the modern era it is seen as one of the most important factors in producing a race-winning car. Research carried out in the Department of Aeronautics at Imperial College London, into flow control techniques and the development of cutting-edge numerical and experimental methods has allowed specific and significant improvements in the aerodynamic design of Formula One racing cars. This has led to reduced lap times and a more competitive racing environment. These advances have also contributed to improving handling, resulting in a safer racing environment. This research has provided the Formula One industry, which has an estimated annual turnover of $2 billion, with a means to employ engineers who have the key knowledge and insights that allow them to continue to innovate in a tightly controlled engineering environment. The Chief Designer or Chief Aerodynamicist in six out of the twelve 2012 F1 teams have carried out relevant research at Imperial College London.
Our research has been key to the development of investor confidence in an emerging UK tidal stream industry. We have contributed to the development and validation of commercial and open- source software for tidal stream system design and our expertise has been instrumental to the successful delivery of major objectives of two national industry-academia marine energy projects commissioned by the Energy Technologies Institute (ETI). Taken together, these outcomes have reduced engineering risks that had been of concern to potential investors. Investor confidence in tidal energy has been increased, as highlighted by Alstom's £65m acquisition of a turbine developer following a key outcome of the ETI ReDAPT project.
Research in the University of Cambridge Department of Engineering (DoEng), which made it possible for the first time to design a 3D compressor blade as a single component, underpinned the design of compressors in Rolls-Royce civil aero engines. Blades designed using the research results yielded fuel efficiency improvements of 0.8% when deployed in Rolls-Royce Trent engines. The efficiency improvements in engines in service are estimated to have delivered savings of 460k tonnes in CO2 emissions and USD 145 million in fuel costs during the assessment period. Rolls- Royce's outstanding order book for engines in which the technology made a significant contribution to efficiency is estimated to be worth GBP 27 billion at list prices as at 31 July 2013; orders received during the assessment period are estimated to be worth GBP 18 billion at list prices.
This case study relates to research supported under contract by Statoil AS, one of the world's largest oil and gas companies, and is focused on two major issues of significance to that industry, namely, the mathematical modelling and analysis of (a) hydraulic two-layer gas/liquid flow in pipe lines and (b) wax formation in the interior walls of pipe lines transporting heated oil. These projects arose out of contacts between senior research staff at the Statoil Research Centre and the Nonlinear Waves group in the School of Mathematics. The theoretical research undertaken was designed to complement the major experimental programmes developed at the Statoil Research Centre and was performed in collaboration with scientists there. The work has provided Statoil with a reliable theoretical framework to contextualise and enable comparison with experimental results and to inform the design of future experimental programmes. In the larger context, the research has played a key role in advancing the capability of Statoil to design and implement more economical, energy efficient, and environmentally safe strategies for gas/oil delivery via extended pipeline networks. Statoil have stated that the benefit of access to robust flow models in the North Sea context is rapidly approaching an economic value of many billions of Norwegian kroner.
Using advanced mathematics and numerical modelling we have demonstrated how fundamental understanding of laminar-turbulent transitions in fluid flows can save energy. From 2008 we helped the cleantech company, Maxsys Fuel Systems Ltd, to understand and improve their technology and demonstrate to customers how it can reduce fuel use by 5-8%. Customers including Ford Motor, Dow Chemical and Findus testify to the impact from financial savings and reduced carbon emissions obtained by installing Maxsys products on industrial burners used widely in many industrial sectors including automotive, bulk chemicals and food. In 2010, Selas Heat Technology Company bought the Maxsys brand to invest in this success.
Work and tool temperature are major issues in abrasive machining. Cooling fluids, usually oil based, are used to control these temperatures. This research aimed to achieve much more effective use of coolant. The established industrial practice was to use very high volumes of oil, under very high pressures. This is an expensive and environmentally unfriendly approach. This research improved coolant flow quality by improving nozzle design and established the underlying physics to improve penetration of coolant into the cutting zone. It then went on to show that it was not only possible, but sometimes it may actually be beneficial, to dramatically reduce coolant flow volume by a factor of up to 20,000. Before industry would adopt these ideas it was necessary to have firm scientific evidence of their validity. This research by the General Engineering Research Institute (GERI) provided that foundation and has led to successful adoption by industry, which has in turn led to both economic and environmental impact. This case study will evidence industrial take-up via specific examples and shows that GERI's research in this area has had a global impact on the training of industrial engineers employing the grinding process.
