| Abstract: | Theoretical study about the dynamics of open swirl injector has been performed. The influence of axial velocity of the liquid in vortex chamber of open swirl injector on the mass flow rate pulsation has been analyzed. The formula for the dynamics of the open swirl injector has been deduced. The dynamics of open and common swirl model injectors was calculated. The results show that the flux fluctuation of open swirl injector is much less than common swirl injector. Moreover, the phase characteristics of open swirl injector is more stable than that of common swirl injector with the increase of frequency. |
