Abstract : This work in this project dealt with large scale scientific computing. Particular attention was given to fluid flow - both compressible and incompressible - chemically reacting flows arising in combustion as well as moving boundary problems. The primary object was to develop efficient numerical methods that could be used for practical engineering problems. The research consisted in the development of appropriate variational formulations, and then inventing stable and accurate discretizations based on the variational methods. In the area of combustion this has lead to an entirely new approach which has proven effective in modelling the very complicated features of chemically reacting flows. (Author)
