On the simulation of laminar strained flames in stagnation flows: 1D and 2D approaches versus experiments
Abstract : The present work is essentially devoted to the simulation of a laminar strained flame using two approaches: 2D realistic and 1D simplified. The studied case corresponds to a laminar burner that creates an upward-oriented round jet of stoichiometric methane–air mixture impacting on a horizontal metal disk. 2D numerical simulations have been performed using the Fluent 6.3 software in the axisymmetric configuration. Detailed thermochemical and transport models are applied. Results of the 2D and 1D simulations are analyzed and compared with experimental data on flow velocity obtained by particle image velocimetry (PIV). Limitations of the classical 1D approach are identified and further commented on. Measurement errors due to the particle slip are evaluated by simulating the particle motion with inclusion of the gravity, Stokes drag, and thermophoretic forces.
