Injection, Atomization, Ignition and Combustion of Liquid Fuels in High-Speed Air Streams.
Abstract
Experimental studies of the penetration, break-up and atomization of transverse liquid and slurry jets were performed. All tests were with an air cross flow at Mach 3.0 with Po = 4 atm. and To = 300 deg K. The processes studied were: (1) the effects of injectant viscosity and surface tension, (2) the performance of an impinging jet injector and (3) the effects of particle loading for a slurry jet with 3-50 micrometer particles. The diffractively scattered light method was employed at these high-density, supersonic conditions to study droplet sizes. The major results are, (1) mean droplet size is approximately 10 microns for injectors of 0.05 in., (2) it has an inverse relation with jet/free stream dynamic pressure ratio, (3) it has a direct relation with orifice diameter, (4) it decreases downstream, (5) transverse variation has no simple pattern and (6) droplet size increases with viscosity.
