    Alternative Aviation Fuels Kinetic Mechanism Development

    Experimental investigations into alternative fuel performance, in flames and jet-stirred reactors provide a wealth of data to aid the development of chemical kinetic models of the combustion process. In this project, these models will be enhanced based on a survey of current literature developments. Sensitivity analysis tools will allow the identification of the most important reactions within the models themselves, and where there is significant uncertainty in the reaction rate data, the GAUSSIAN 09 software package will be employed to determine thermodynamic and structural properties thus allowing improved estimations of the rate parameters for these important reactions.

    Ultra-low emission technologies in combustion for power generation

    RJM-international is a medium sized technology provider offering state-of the-art emission reduction solutions for the power and industrial energy sectors. Core work is based on emissions reductions, primarily NOx for fossil fuels and fossil fuel replacements such as wood biomass. The projects  involved are worldwide and our clients include some of the world’s largest power generators. We are looking for an EngDoc to work on CFD modelling capability.  All projects are based on detailed engineering analysis and part of that is the use of CFD. As designs improve (currently achieving industry best reductions in NOx) the CFD codes are struggling to keep up. For instance the modelling of the ultra-low NOx gas burner is problematic as the Fluent code does not handle the flue gas recirculation correctly and seriously under-predicts the  NOx.  There are several areas where development is needed.

    We are looking for someone wanting a career in CFD modelling. The opportunity with RJM will provide the successful candidate an excellent training within a technology led engineering company with world beating products. Feedback from Year-in-Industry under-graduate placement supervisors has praised the opportunity working with RJM.  It is highly probable that a successful placement with RJM would lead to a job opportunity.

    The Studentship provides an in-depth four year training programme with a non-taxed stipend of up to £18,000 per year; much higher than a conventional PhD, plus international travel for conferences and attending summer schools held in China, India and South Korea.

    Ignition and flame stability for flexible and efficient operation of power plants

    Worldwide consumption of energy has increased dramatically over the past 100 years and the combustion of fossil fuels has played a significant role in providing the required energy source. In a power plant, pulverised fuel is delivered through multiple burners into a furnace where combustion occurs. Ignition of pulverised fuel particles is the first stage in the combustion process where the particles are heated rapidly and a visible flame is developed. Successful ignition and flame propagation is important for achieving near burner flame stability. Improving the fundamental understanding of ignition phenomena can lead to better plant performance and flexibility.

    This project will develop an ignition model approach using computational fluid dynamics for the combustion of pulverised coal. CFD can be used to assess performance and limitation of a burner but is limited by simplistic models representing the aerodynamics and combustion chemistry. An understanding is required to determine the ignition mechanism of solid-fuel particles and a model is needed to establish the possibility of ignition and flame propagation of a solid-fuel flame.
