Abstract

A possibility is demonstrated to appear oscillations of fluid discharge and pressure within a tube feeding the large-discharge stage of a two-stage injector. The oscillations can also appear in conventional fluid centrifugal burner provided that twisting chamber of the injector is connected with the feeding tube. Experimental results are described to estimate pressure values for the injectors discussed. A computation technique is offered to evaluate two-stage injector geometrical and operational parameters for throttling and bypassing modes of functioning.
