Abstract:

An experimental investigation was completed to examine the influence of injector design changes on the resultant drop size for like impinging doublet injectors. The variables studied are injection velocity, orifice diameter, impingement angle, stream alignment, orifice length to diameter ratio, and orifice surface finish. Droplet data were obtained using water as the propellant simulant in conjunction with a back-lighted photographic technique. It was found that no detectable change in drop size resulted from changes in orifice LD or orifice surface finish within the ranges investigated. Stream misalignment was found to increase drop size when the other injector parameters remained constant. Author
