Three PhD studentships are available from October 2013 on a collaborative project between Cambridge, Leeds, Durham and a consortium of companies interested in inkjet printing and drop delivery. Two of these studentships will be based at the University of Leeds and one at Durham University, but students will work collaboratively with PhD students, post-docs and senior researchers across the three institutions. All projects concern inkjet printing of complex colloidal fluids, from the formation of drops to the final state of a dried deposit on a substrate.
This project will study the fluid motions within drops deposited by inkjet printers, through the use and development of sophisticated numerical methods and mathematical models for direct simulation of colloidal suspensions during drop deposition. In particular we are interested in understanding fluid and suspended particle motions in various scenarios including the impact, spreading and evaporation of single drops on non-porous solids, coalescence of consecutive drops to form continuous tracks, and the evaporation versus imbibition of drops deposited on porous substrates. The studentship will be co-supervised by Dr Oliver Harlen (Mathematics) and Dr Mark Wilson (Mechanical Engineering) at the University of Leeds.
Each studentship will be for a period of 42 months from October 1 2013, though other start dates may be agreed. The stipend will be at the EPSRC rate, currently £13,590 p.a. The positions are restricted to applicants liable for UK home fees. Applications for all three posts should be sent to:
phd@engineering.leeds.ac.uk
and should include a CV and cover letter stating which position(s) you wish to apply for and explaining why you are interested in and qualified for the position(s). Please provide the names and contact details of two referees and ask them to send references to phd@engineering.leeds.ac.uk by the closing date.
For informal enquiries please contact Dr Oliver Harlen (o.g.harlen@leeds.ac.uk) or Dr Mark Wilson (m.wilson@leeds.ac.uk)
Polymers and Industrial Mathematics
Research in the Polymers and Industrial Mathematics group focuses on the mechanics of polymers and other complex fluids, free-surface flows and inverse problems. We are also concerned with the development and implementation of novel numerical and computational solution methods for both ordinary and partial differential equations, from fundamental aspects (the theoretical analysis of numerical methods) to problem-specific aspects (the design, development and practical implementation of novel algorithms). Within the polymer area, we conduct fundamental research into fluids that have a complex microstructure, such as polymer melts and solutions and colloidal dispersions.
Our research combines methods from molecular physics and continuum mechanics to develop multiscale models that link together the microscale motion of individual molecules to the flow behaviour of the bulk material. An important class of industrial flow problems are those involving free surfaces, such as in inkjet printing, film coating and bubble growth in polymeric foams. We also work on a diverse range of inverse problems in heat transfer, porous media, fluid and solid mechanics, acoustics and medicine. This is a strongly interdisciplinary subject and much of our research involves collaborations with independent research groups in science and engineering departments both at Leeds and worldwide, as well as with industry.
