Summary on Grant Application Form
Today, most of the energy is provided from the combustion of fossil fuels, a resource that will only last for a limited amount of time. Furthermore, its combustion creates poisonous products that eventually lead to global warming. To further satisfy the need for affordable energy and to reduce the side-effects, a detailed knowledge of the combustion process must be acquired and be applied to improve the technical devices. The development of better furnaces and combustion engines requires to set up and test new designs before improving them further -- and testing them again. With the steady growth of computer power, combustion simulation techniques have emerged that allow to perform major parts of the testing on computers. This significantly reduces the development costs and at the same time allows for a more elaborate investigation and further improvement of combustor designs.The proposed work will focus on taking these computational techniques further. It will apply and improve a mathematical approach where all the relevant features of the flow and combustion are simulated (Large-Eddy Simulation, LES), relying on a simplified treatment for additional phenomena. This simplified treatment will be tested and improved against reference information from an additional experiment and a costly full simulation (Direct Numerical Simulation, DNS). To the investigators knowledge, this will be the first attempt to compare LES results to both experimental and DNS data.The results of the work proposed are expected to deepen insight into the test-flame, and to validate and to improve the simplifications applied, leading to better simulation techniques for turbulent combustion. In the end, these are expected to become a basis for tools enabling combustor designers to provide cheap, safe and environment friendly energy.
