In the context of coaxial swirl injectors used in liquid bipropellant rockets, a detailed experimental study has been made on the mutual interaction between thin coaxial, conical liquid sheets. As the flow rates are increased, the sheets move close to each other and merge at a definite flow condition. The presence of the inner jet influences the behavior of the outer jet, even before merging. The merging and separation processes exhibit hysteresis. This leads to drastic variations in spray characteristics depending on the approach to the hysteresis regime. Many of these features as well as those on the movement of the contact point can be traced to changes occurring in the static pressure in the cavity between the two sheets. © 1998 American Institute of Physics.
