A fully coupled high‐order Discontinuous Galerkin method for diffusion flames in a low‐Mach number framework

We present a fully coupled solver based on the discontinuous Galerkin method for steady-state diffusion flames using low-Mach approximation of governing equations with one-step kinetic model. The nonlinear equation system is solved Newton–Dogleg and initial estimates flame calculations are obtained from flame-sheet Details spatial discretization presented. tested reactive nonreactive benchmark cases. Convergence studies presented, we show that expected convergence rates obtained. used calculating differentially heated cavity configuration, which validated against solutions. Additionally, two-dimensional counter calculated, results compared self-similar one dimensional solution said configuration.
