The modeling of a laboratory natural gas-fired furnace with a higher-order projection method for unsteady combustion
Description: A higher-order, embedded boundary projection method for axisymmetric, unsteady, low-Mach number combustion is used to model a natural gas flame from a 300 kW IFRF burner in the Burner Engineering Research Laboratory (BERL) at Sandia National Laboratory under hot wall conditions. The numerical predictions presented are the late simulated-time results of a computation of unsteady flow in the furnace. The predictions are compared both with measurements completed in the BERL as part of the GRI SCALING 400 Project and with results from a steady-state axisymmetric reacting flow code in order to evaluate the combustion model and the numerical method. The results compare favorably with the experimental data.
