Computational Modelling of Molecular Dynamics in Elastomeric Seal Leakage PhD

An exciting PhD position sponsored by EPSRC and Airbus in Computational Modelling of Molecular Dynamics in Elastomeric Seal Leakage is open for applications. You will construct a novel model of elastomeric materials to simulate sliding, rolling, and oscillating motion, while investigating the nanotribology properties with a Molecular Dynamics model. The emphasis is on the understanding of the relative importance of various material properties and other key factors on the seal leakage. The position also provides a rich opportunity to present the research results at international conferences and to work across various research groups within the University. Read moreRead less

One of the key contributors of seal leakage is attributed to the dynamic operation and environmental conditions of the hydraulic system. During the life cycle of the seal, the elastomeric material is submitted to excessive wear which in turn increases the leakage rate, thus the overall performance of the hydraulic system deteriorates.  

Tribology, the study of friction and wear is mainly carried out through empirical and experimental practices. In recent years computational tribology has seen an increase in research interests by both the physics and engineering research communities. Cutting-edge research in computational frameworks has seen industrial interest in developing numerical models and workflows for the study of tribological properties. The insights of friction and wear characteristic from these simulations is used to improve the design of mechanical components such as seals. The computational analyses are performed in both the continuum and molecular realm. 

Cranfield University excels in strategic and applied research. In the latest 2014 Research Excellence Framework (REF), 81% of our research was considered ‘world leading’ or ‘internationally excellent’ in its quality. Cranfield is a ‘Top 5’ research institute, based on commercial income and it is the only Post Graduate exclusive University of the UK.

Airbus is a global aircraft manufacturing company with roots in Europe, which includes in its portfolio a modern and comprehensive family of civil airliners. Airbus has a well-established track record in industrial research and technology development in the aerospace sector. Technological progress through research and innovation allows the company to contribute to civil aviation’s commitments to more fuel efficient and environmentally friendly operations.

The project looks at developing Molecular Dynamics models that can simulate nanotribological properties of seals and seal-systems, which then can be employed to enhance the modelling performance (accuracy & cost) of continuum models such as Computational Fluid Dynamics, Structural Dynamics, and Fluid Structure Interaction.

You will belong to a new Airbus Landing Systems Engineering Centre (LASEC) at Cranfield University, as well as the Centre for Structures Assembly and Intelligent Automation within The School of Aerospace, Transport, and Manufacturing. Working within LASEC will enable frequent contact with Airbus Engineers with a valuable physical understanding of the processes in the application area. Funding for conference travel exists. Relocation to Airbus in Filton, Bristol, for a minimum of three months during the 4-year PhD project will be an opportunity for further immersion into the company.

Apart from the connections to the funder of the project, Airbus, other aerospace companies will be interested in your work. The aeronautical sector has been growing steadily and traffic has more than doubled since 2000. The air traffic is forecast to double again in the next 15 years. It is estimated that additional 40000 aircraft will be needed in the next 20 years with 76% of serving the short range market. Successful completion of the PhD will greatly enhance the chances of employability in other sectors such as automotive where Rolls Royce has been strategically working with Cranfield for many years.
