Design of D-B Injectors for Increasing Propulsive Force in Jets 2005-01-3388

In this work the fundamentals of centrifugal injector calculation is reviewed and new design procedure is proposed for liquid-liquid injectors, based on both theory and experimental results. Then some special conditions related to dual based liquid-liquid injectors are studied and the corresponding results were considered in design manipulation. The behavior of injector in various service conditions, such as mutual effects on twin spray envelopes in dual-base injector is investigated, then the design procedure is presented based on obtained results. Finally the computer program for designing this sort of injector is proposed. Using this program, some injectors were designed and tested. The results were presented in details in this paper.
