A depth-averaged model for non-isothermal thin-film rimming flow (2013)
Journal Article
Kay, E., Hibberd, S., & Power, H. (2014). A depth-averaged model for non-isothermal thin-film rimming flow. International Journal of Heat and Mass Transfer, 70, https://doi.org/10.1016/j.ijheatmasstransfer.2013.11.040

A model for non-isothermal shear-driven thin-film flow on the inside surface of a stationary circular cylinder is presented. Motivated by an application to film flow in an aero-engine bearing chamber the model extends lubrication theory analysis of t...

Pragmatic optimisation methods for determining material constants of viscoplasticity model from isothermal experimental data (2013)
Journal Article
Rouse, J. P., Hyde, C. J., Sun, W., & Hyde, T. (in press). Pragmatic optimisation methods for determining material constants of viscoplasticity model from isothermal experimental data. Materials Science and Technology, 30(1), https://doi.org/10.1179/1743284713Y.0000000277

A procedure to estimate material constants for the unified Chaboche viscoplasticity model from experimental data has been published elsewhere; however several critical assumptions are made to enable this and potential numerical problems can limit the...

Vibration suppression and coupled interaction study in milling of thin wall casings in the presence of tuned mass dampers (2013)
Journal Article
Kolluru, K. V., Axinte, D. A., Raffles, M. H., & Becker, A. A. (2014). Vibration suppression and coupled interaction study in milling of thin wall casings in the presence of tuned mass dampers. Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 228(6), https://doi.org/10.1177/0954405413508769

Damping of machining vibrations in thin-wall structures is an important area of research due to the ever-increasing use of lightweight structures such as jet engine casings. Published literature has focussed on passive/active damping solutions for op...

Finite element investigation of the effect of spina bifida on loading of the vertebral isthmus (2013)
Journal Article
Quah, C., Yeoman, M. S., Cizinauskas, A., Cooper, K., McNally, D., & Boszczyk, B. (2014). Finite element investigation of the effect of spina bifida on loading of the vertebral isthmus. Spine Journal, 14(4), https://doi.org/10.1016/j.spinee.2013.08.040

Background: Spondylolysis (SL) of the lower lumbar spine is frequently associated with spina bifida occulta (SBO). There has not been any study that has demonstrated biomechanical or genetic predispositions to explain the coexistence of these two pat...

Usability of Geographic Information: current challenges and future directions (2013)
Journal Article
Brown, M., Sharples, S., Harding, J., Parker, C., Bearman, N., Maguire, M., Forrest, D., Haklay, M., & Jackson, M. (2013). Usability of Geographic Information: current challenges and future directions. Applied Ergonomics, 44(6), https://doi.org/10.1016/j.apergo.2012.10.013

The use of Geographic Information or GI, has grown rapidly in recent years. Previous research has identified the importance of usability and user centred design in enabling the proliferation and exploitation of GI. However, the design and developme...

It is demonstrated that a combination of microsecond transient photocurrent measurements and fi lm morphology characterization can be used to identify a charge-carrier blocking layer within polymer:fullerene bulk-heterojunction solar cells. Solution-... Read More about Linking vertical bulk-heterojunction composition and transient photocurrent dynamics in organic solar cells with solution-processed MoOx contact layers.

Inertial effects at moderate Reynolds number in thin-film rimming flows driven by surface shear (2013)
Journal Article

In this paper, we study two-dimensional thin-film flow inside a stationary circular cylinder driven by an imposed surface shear stress. Modelling is motivated by a need to understand the cooling and film dynamics provided by oil films in an aero-engi...

We investigate the quasi-static simple shear flow of a two-dimensional assembly of cohesionless particles using discrete element method (DEM) simulations. We focus on the unsteady flow regime where the solid would experience significant evolution of... Read More about Discrete element modelling of material non-coaxiality in simple shear flows.
