Summary on Grant Application Form
The earlier methods of cut-and-try for engine, especially combustor, design improvements are becoming very expensive. To produce cost effective optimally performing engines, the relevant industries are leaning towards computer simulations for design modifications and optimization. Accuracy of the simulations, thus the performance of the final device, strongly depends on the mathematical models used. Current combustion models are proving to be inadequate to predict accurately the behaviour of lean flames. Future engines will operate on fuel lean conditions in order to meet pollutant emission targets. The inadequacy of current combustion models to handle the future technology change is because of our limited understanding of turbulence/chemistry interaction. Carefully conducted direct numerical simulations of turbulent flames will greatly enhance our understanding of this difficult problem. The equipment requested in this proposal will help us to conduct such high fidelity simulations and to construct engineering-predictive models via detailed interrogation of the numerical data sets. These simulations will help us to devise and improve strategies for very large simulations using the UK's national resources. These very large simulations will further our understanding and confidence levels on predictive models. These predictive models can then be incorporated into the CFD codes used in industry. The compute farm requested here will also help us to conduct large eddy simulations (LES) of turbulent flames.
