Abstract: A parallel Adaptive Mesh Refinement (AMR) algorithm is proposed and applied to the predictions of both laminar and turbulent steady non-premixed compressible combusting flows. The parallel solution-adaptive algorithm solves the system of partial-differential equations governing two-dimensional axisymmetric laminar and turbulent compressible flows for reactive thermally perfect gaseous mixtures using a fully coupled finite-volume formulation on body-fitted multi-block quadrilateral mesh. Numerical results for co-flow laminar and turbulent diffusion flames are described and compared to available experimental data. The numerical results demonstrate the validity and potential of the parallel AMR approach for predicting both fine-scale features of laminar and complex turbulent non-premixed flames.

Keywords: parallel solution-adaptive algorithm; AMR; adaptive mesh refinement; laminar combustion; turbulent combustion; non-premixed flames; diffusion flames; combusting flows.
