Investigation of turbulent flame kernels using DNS on clusters: Best student paper award: First prize

Abstract

A parallel code for the direct numerical simulation (DNS) of reactive flows using detailed chemical kinetics and multicomponent molecular transport is presented. This code has been used as a benchmark on several commodity hardware clusters including two large systems with current state-of-the-art processor and network technologies, i.e. up to 180 Alpha EV68 833 MHz and up to 400 AthlonMP 1.4 GHz CPUs have been used, which are arranged in dual-nodes with Myrinet-2000 interconnect in both cases. The other part of the paper presents the results of an investigation of flames evolving after induced ignition of a premixed mixture under turbulent conditions. © Springer-Verlag Berlin Heidelberg 2003.
