Computational fluid dynamics (CFD) offers a major opportunity for the development and application of GRID technology in engineering.

In the present work a parallel combustion DNS code called SENGA was used to investigate flame kernel growth in a turbulent environment. Due to the nature of DNS, simulations are becoming more demanding, both in terms of the physics to be simulated and the levels of temporal and spatial resolution requirement. Therefore, current grid technologies have been used for CFD to investigate simulation performance in terms of user friendly job submissions and data access. These technologies include Globus and Condor software. A Condor pool, consisting of an eight processor PC cluster, was set up. Finally, distributed data sets were generated and analysed to look at the flame surface structure in the form of component flame surface normals.
