The current work uses a multi-regional method for improving the computing performance of large-scale combustion simulations. In this manner, the solution of the isothermal flow within the burner is treated separately from the domain with combustion reaction. For the fresh gas flow within the nozzle only the Navier-Stokes equations for a non-reactive, fixed composition flow are solved, whereas the combustion model accounting for the chemical reactions is enabled in the ignition zone downstream of the burner. Because the chemistry solution takes a major part of the total computing time, the approach saves that part of execution time for the computing nodes located within the nozzle, where no chemical reaction occurs. In the present study, the potential of this methodology has been assessed by large eddy simulation (LES) of a model burner operated with a premixed methane/air flame. The multi-regional simulation showed consistent results with data obtained from the conventional single-regional computation. It however has been proven to be considerably faster than the comparable single-zonal LES, denoting an improved computing performance.
