Research Interest: Modelling of Biofuels
Supervisor: Mohamed Pourkashanian

 

     

My PhD project is based on the development of a chemical kinetic mechanism for the oxidation of a mixture of kerosene and oxygenated compounds, biofuels. The existing mechanism AFRMv1.2, created for kerosene, will be updated and eventually modified, as the addition of biofuel takes place. The oxygenated compounds considered in this work will be esters obtained from vegetable oil. A different type of fuel can be also taken into account, synthetic kerosene produced through the Fisher-Tropsch process.

Once the mechanisms are complete, simulations will be achieved and compared with experimental results to test the reliability of the models.

Research Interest: Gas Turbine Cooling
Supervisors: Derek Ingham, Andrew Gordon and Mohamed Pourkashanian

     

Increasing development of high performance aero and industrial gas turbine engines accompanied by increasing combustor temperature which is much higher than melting point of component metals in its environs. Thus, the gas turbine and combustor and the turbine blade walls continually require optimum cooling performance to cope with the harsh combustor temperature.

This research involved detailed CFD investigation of full-coverage effusion film cooling with and without impingement cooling. The predicted computational results will be compared with the available experimental data.

Project Title: Thermochemistry and Kinetic modelling of Bio-fuel Combustion
Supervisors: Prof M Pourkashanian, Prof A Williams, Dr K J Hughes

 

     

Recent concerns over the disadvantages of fossil fuels have raised the need to look at alternative fuels as a new source of energy. Sustainable and environmentally friendly fuels are being considered for this purpose, from which biofuel and Ficsher-Tropsch (FT) fuels have potential. To simulate the performance of any engine running on such fuels and evaluating combustion characteristics, a fuel model is required which would include the fundamental data on its chemistry, in particular the reaction rate parameters.

Although coming from different sources, almost all types of biofuels consist of mixtures of saturated and unsaturated methyl esters. Considering the size of these oxygenated hydrocarbons, which can vary from 12 to 20 carbons in chain, applying traditional experimental methods to obtain the reaction rate parameters are not feasible, therefore, using computer based calculations is the best and only solution. Using Quantum Mechanics (QM) and Molecular Mechanics (MM) this project involves assessing the behaviour and properties of such fuels, developing their reaction mechanism and eventually simulating their combustion.

Research Interest: Combustion Modelling of Alternative Fuels in Aero-Engines
Supervisor: Prof. M. Pourkashanian, Dr D. Borman, Dr L. Ma, Prof. C.W. Wilson (external supervisor)

 

     

Recent concern over energy security and environmental considerations have highlighted the importance of finding alternative aviation fuels. Alternative fuels have been studied widely for automotive combustion, but now attention is focusing on the aircraft industry.

The research is focused on the CFD modelling of alternative fuels combustion in aircraft engine. The combustion process is investigated using a commercial CFD solver Fluent. With recent developments in processor speeds and solver improvements, CFD has been successfully validated and used as a tool for optimizing combustor technology.

During research different turbulence and combustion models are studied for accuracy of combustion phenomena predictions, with special consideration to Large Eddy Simulation (LES) model.
