Flame Kernel Interactions in a Turbulent Environment

Abstract

Results are presented from a parallel DNS combustion code called SENGA. The code solves a fully compressible reacting flow in three dimensions. High accuracy numerical schemes have been employed which are explicit 10th order central finite differences in space, a third order explicit Runge-Kutta method in time and parallel implement at ion is achieved through the Message Passing Interface (MPI). Turbulence is generated numerically for a 128(exp 3) simulation with Re = 30 and a 384(exp 3) simulation with Re = 130. Finally, results are presented and discussed for simulations with different initial non-dimensional turbulence intensities ranging from 5 to 23.
