The goal of the present grant was to develop laboratory model combustors and experimental methodology suitable for the acquisition of the desired information. In a previous grant 78-3586, a premixed laboratory combustor, the Opposed Jet Combustor, was developed and a data base was established in both a gaseous non-reacting and reacting system as well as a hydrodynamic water system. In addition, a non-premixed model swirl-stabilized laboratory combustor, the Dilute Swirl Combustor DSC, was developed and tested, and a data base was established for non-reacting as well as reacting gaseous-fired conditions. The present grant was directed to operating the DSC on spray-atomized liquid fuels, to establishing a droplet sizing capability that would lead, over the five-year duration of the grant, to in situ measurements of drop size and drop velocity as well as gas velocity within the DSC, and to the study of turbulent transport in swirl-stabilized, liquid-fuel spray-atomized reacting flows. In particular, the objectives of the program were 1 To develop and verify a capability to conduct in situ measurements of droplet size and velocity 2 To operate the DSC with a liquid, spray-atomized twin-fluid nozzle and 3 To conduct supplementary studies in support of Air Force laboratory interests in complex flows.
