The Modeling of a Laboratory Natural Gas - Fired Furnace with a Higher - OrderProjection Method for Unsteady Combustion
نویسنده
چکیده
A higher-order, embedded boundary projection method for axisymmetric, unsteady, low-Mach number combustion is used to model a natural gas ame from a 300kW 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 ow 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 ow code in order to evaluate the combustion model and the numerical method. The results compare favorably with the experimental data.

متن کاملAn Embedded Boundary Method for the Modeling of Unsteady Combustion in an Industrial Gas-Filled Furnace
A new methodology for the modeling of unsteady, nonpremixed, axisymmetric reacting ow in industrial furnaces is presented. The method is an extension of previous work by the authors to complex geometries, multistep kinetics mechanisms, and realistic properties, especially thermochemical data. The walls of the furnace are represented as an embedded boundary in a uniform, rectangular grid. The gr...

This paper presents some of the results of the modeling and simulation of an industrial furnace under the conventional combustion as well as under the highly preheated and diluted air combustion (HPDAC) conditions. The results are obtained using a computer program written by authors in FORTRAN language. It was found that, the HPDAC offers a more uniform and relatively moderate gas temperature p...
