Abstract:
Experimental data were obtained for the purpose of
validating multiphase combustion models and submodels. A
reference spray combustor was fabricated to permit
well-defined input and boundary conditions, enabling
measurements to characterize the fuel spray, combustion
air, wall temperatures, gas temperatures, and species
concentrations. The level of complexity of the reference
spray combustor is consistent with a benchmark case in
which the level of coupling between the flow field and
the remaining physics (e.g., chemical reactions, heat
transfer) is not as extensive as in the complete system,
but is also not insignificant. The characteristics
(i.e., size, velocity, volume flux, etc.) of the
methanol fuel spray were determined using phase Doppler
interferometry. Fourier transform infrared spectroscopy
was used to measure the species concentrations in the
reactor emissions, and the conversion of methanol in the
reactor. Thermocouple measurements provide gas
temperature data at the reactor exit. Particle image
velocimetry was used to characterize the inlet
combustion air, and also to provide validation data
farther downstream.
