Benchmark Data for Fuel Atomization and Combustion Models



J F. Widmann, S R. Charagundla, Cary Presser


Experimental data were collected for the purpose of validating multiphase combustion models and submodels. A spray combustor was fabricated that permits well-defined boundary and input conditions, and measurements were carried out that characterize the fuel spray, wall temperatures, gas temperatures and species concentrations at the reactor exhaust. The operating conditions for the baseline case were defined by NIST personnel and industrial collaborators involved in model development. A methanol spray, generated with a pressure-jet nozzle, was studied with phase Doppler interferometry to measure the size, velocity, number density, and mass flux of the fuel droplets. Fourier transform infrared spectroscopy was used to measure the species concentrations in the reactor emissions. The conversion of methanol in the reactor was found to be 80%.
