Date posted: 12/08/2009 Researchers from ETH Zurich have simulated autoignition in a turbulent flow using a supercomputer with up to 65,000 processors in one of the largest reactive flow simulations to date. The results could help to develop better models and reduce the high cost of real experiments. A team of researchers from the Laboratory of Aerothermochemistry and Combustion Systems (LAV) headed by Professor Konstantinos Boulouchos recently presented initial results of one of the largest reactive ?Direct Numerical Simulations? (DNS) to date. The simulated autoignition of hydrogen in a turbulent hot air coflow is essentially a laboratory experiment performed on the computer. The fuel ignites by itself when its pressure and temperature is high enough. ?The main advantage of such a numerical simulation over a ?real? experiment is that data like the flow velocity, temperature, pressure and concentration of the individual chemical components can be measured accurately with a high temporal and spatial resolution. It would simply be impossible to obtain such detailed information in a real experiment?, explains Christos Frouzakis, head of the DNS group at LAV.
