Bristol research helps reduce the threat to people and property from snow avalanches

Summary of the impact

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.

13. Increased safety and efficiency of oil and gas process designs from improved flow assurance

Summary of the impact

Multiphase flow research at Imperial has developed bespoke software code, and provided unique data for validation of commercial codes used for oil-and-gas design. This research has enabled global oil companies (e.g. Chevron) to undertake successfully the design of deep-water production systems requiring multi-billion pound capital investments. This research has also allowed SPT Group (now owned by Schlumberger), one of the largest software (OLGA) providers to the oil industry, to maintain their position as market leaders.

Optimal design of flow handling systems using computational fluid dynamics

Summary of the impact

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.

Advanced fluid flow modelling improves the efficiency of industrial burners

Summary of the impact

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.

17. Improving the Aerodynamic Performance of Formula One Racing Cars

Summary of the impact

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.

Electrostatic measurement of pulverised fuel flow

Summary of the impact

Coal fired power stations will be a major element of global power generation for the foreseeable future. Measurement, and hence control, of pulverised fuel flow is a vital technology for the efficient and green operation of coal fired power stations. Balancing fuel delivery and combustion stoichiometry increases boiler efficiency and reduces emissions. Research in this area carried out at Teesside University was adopted by ABB Ltd and led to the commercial development of new powder flow measurement systems (PfMaster technology) installed in power stations around the world. Quantifiable economic benefits of the installations to date amount to >£3.4 M with concomitant environmental benefits of significant reduction in CO2 and NOxemissions and solid waste disposal burdens.

UOA10-01: Computational fluid dynamics: the Rolls-Royce HYDRA code for jet engine design

Summary of the impact

Rolls-Royce uses the HYDRA computational fluid dynamics (CFD) code for the design of all of its new gas turbine engines. The HYDRA CFD package, including the mathematical theory behind it, was developed by Professor Mike Giles and his research team in the period 1998-2004 at the University of Oxford, and subsequently transferred to Rolls-Royce, forming the basis of the RR corporate CFD strategy with an investment of over 100 person years in development.

Since 2009, HYDRA has become the standard aerodynamic design tool across Rolls-Royce, and has been used to design Rolls-Royce's Trent 1000 engine and the newer Trent XWB. HYDRA has enabled Rolls-Royce to save over [text removed for publication] in test rig expenses, provides superior accuracy compared to its competitors such as FLUENT, and has contributed to increases in engine efficiency of up to [text removed for publication], which in turn has led to higher sales and increased revenue for Rolls-Royce.

Improving Fluid Delivery in Abrasive Machining

Summary of the impact

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.
