Combustion DNS (Direct Numerical Simulation) provides detailed and instantaneous information on the behaviour of the flame. In the present work the DNS code SENGA is used to investigate the propagation of spherical flame kernels in a turbulent field. Prior to initialising large-scale parallel simulations, a series of smaller scale serial computations must be done in order to establish the key parameters and reaction constants.

The NIMROD suite provides the ideal platform for carrying out these tasks, allowing full automation of the initial parameter sweep and optimisation of the governing constants prior to the large-scale simulations..
