Our world's energy needs are ever growing due to industrialization in developing countries, increasing population and improved standard of living. At present nearly 80% of the world's energy needs are supplied by fossil fuels (coal, oil and gas). It is estimated that fossil fuel reserves will continue to supply a major share of world's energy needs for many more years to come. However, there is a growing concern that combustion of fossil fuels is causing pollution and leading to global warming and climate change. For this reason, there is an ongoing push towards cleaner and more efficient combustion (in engines and other industry applications) to reduce emissions.
My research work focused on developing accurate and computationally efficient (fast) models and algorithms for simulating combustion processes. During my Ph.D. at Cornell university, I developed several computational models and algorithms for accurate and efficient simulation of combustion processes. These algorithms were validated using experimental data, were shown to yield ten to hundred times speedup compared to some of the existing methods, and were also implemented, tested and shown to perform well on over 9,000 core clusters. These tools are now freely available for public and commercial use at our research group site. Some of these algorithms are being incorporated in commercial packages which will enable their direct use in the industry for engine design and manufacturing.
