INTRODUCTION

Coventry University has been voted ‘Modern University of the Year’ three times running by The Times/Sunday Times Good University Guide. Ranked in the UK’s top 15 (Guardian University Guide), we have a global reputation for high quality teaching and research with impact. Almost two-thirds (61%) of our research was judged ‘world leading’ or ‘internationally excellent’ in the Research Excellence Framework (REF) 2014. By joining the University’s Faculty of Engineering, Environment and Computing (EEC), you will benefit from state-of-the-art facilities and partnerships with some of the biggest names in industry, including Jaguar Land Rover, GE Aviation, Cummins and Intel.

THE PROJECT

With the depletion of fossil fuels, we are investigating into the feasibility of blended fossil-/biodiesel-fuels with minimal modifications to IC engines. However, biodiesel is highly productive of NOx. Thus, the interest in reducing NOx from diesel engines is significantly important. SCR technology is one of the most cost-effective and fuel-efficient technologies available to help reduce diesel engine emissions, which can reduce up to 90% of NOx emissions, 90% of HC and CO emissions, and 50% of PM emissions.

Studies assume that all the reductant is evaporated at the entry of the SCR domain because of the long mixing length, but this may not be the case in the close-coupled system with a much shorter mixing length. Although the droplet deposition problem could be avoided by other means, such as calibration, this may not work at extreme operating conditions, e.g. low mass flow rate and low temperature. Since the active SCR system will be the major emissions control device in the next generation diesel engines, it is important to have a thorough understanding of such failure modes and find ways to minimize its impact on product development and warranty. This study will be focused on injection of different reductants’ droplets of various fractions into SCR to investigate their impact on system efficiency.

FUNDING

  • International-scholarship funded students are welcome, and greatly encouraged to apply.
  • Self-funded students can apply.
  • For the academic year 2018/19, any English student who is not part of a research council can borrow up to £25,000 to help cover the cost of their PhD tuition fees. Further details can be found here.
  • The project has a great potential to be partly-funded by Coventry University Research Institute for Future Transport and Cities, upon completion of first milestones and receipt of industrial part-fund.

BENEFITS

  • Our research strategy is underpinned by a £250m investment in research and facilities
  • Dedicated Doctoral College and Centre for Research Capability Development deliver high quality professional support for researchers, from PhD to Professor
  • Free training: research career planning, managing your doctorate, research communication skills, research ethics, research impact, research integrity, research methods and research supervision
  • Coventry is a member of the Doctoral Training Alliance (DTA), the largest multi-partner and only nationwide doctoral training initiative of its kind.

ENTRY REQUIREMENTS

Successful applicants will have:

  • A minimum of a 2:1 first degree in a relevant discipline/subject area with a minimum 60% mark in the Project element or equivalent with  a minimum 60% overall module average.
  • In the event of a first degree classification of less than 2:1, a Masters Degree in a relevant subject area will be considered as an equivalent. The Masters must have been attained with overall marks at minimum merit level (60%). In addition, the dissertation or equivalent element in the Masters must also have been attained with a mark at minimum merit level (60%).

or

  • a taught Masters degree in a relevant discipline, involving a dissertation of standard length written in English in the relevant subject area with a minimum of a merit profile: 60% overall module average and a minimum of a 60% dissertation mark

PLUS

  • the potential to engage in innovative research and to complete the PhD within a three-year period of study
  • a minimum of English language proficiency (IELTS overall minimum score of 7.0 with a minimum of 6.5 in each component)

Additionally:

  • A good knowledge of chemical engineering, including: organic and inorganic synthesis, reaction kinetics.  
  • Previous experimental and modelling/analytical experience in the subject would be qualifying criteria.
  • Experience of (or a willingness to quickly learn about) computational modelling is needed.
