Abstract

Pintle injectors have been developed for applications in rocket propulsion, but could potentially have high flowrate in other applications due to their relative simplicity. The spray from a pintle injector is formed from the collision of radial jets of fluid issuing from the center of the pintle post with an annular sleeve of fluid travelling axially along the post. The resultant interactions produce a conical spray similar to a hollow cone swirl atomizer. This chapter reviews historical applications of pintle injectors and theoretical bases for their design.
