Sažetak(ne postoji na srpskom) In this work the fundamentals of swirl injector calculation is investigated and new design procedure is proposed. The design method for double-base liquid-liquid injectors is presented based on this theory and experimental results. Then special conditions related to double based liquid-liquid injectors are studied and the corresponding results are applied in design manipulation. The behavior of injector in various performing conditions is studied, and the design procedure is presented based on obtained results. A computer code for designing the injector is proposed. Based on this code, four injectors are manufactured. A specialized laboratory was setup for the measurement of macroscopic spray characteristics under different pressure such as homogeneous droplet distribution, spray angle, and swirl effect. Finally, through phase Doppler analyzer cold test, the microscopic characteristics of injectors spray are also obtained and measured. The results which will be explained in detail are satisfactory.
