Özet
Hydrogen supersonic combustion in a duct was simulated numerically using a Navier-Stokes code. Simulation conditions corresponded to the LAERTE experiments: a cold hydrogen jet was injected along the duct axis into a hot flow of vitiated air. A simplified axisymmetric configuration was accepted for the simulations. A parametric study was carried out to investigate the effect of uncertainties of the experimental conditions (flow total temperature, wall thermal state) and the influence of the modeling factors (chemistry kinetic model, turbulent Prandtl number, mesh adaptation). Simulation results were systematically analyzed and compared with experimental data on the wall pressure, flow static temperature, flow speed, and OH radical concentration. © 2003 by CNRS-LCSR, MBDA France, ONERA.
