Abstract

Impinging-jet injectors are commonly used in liquid-propellant rocket engines. Previous theoretical studies on sheets formed by two impinging liquid jets have largely ignored the affect of liquid viscosity, however, several experimental results have illustrated that liquid viscosity could greatly influence sheet characteristics. This paper proposes an improved theoretical analysis model for two viscous liquid impinging jets, in which viscosity and energy dissipation are taken into account; experiments were also performed to validate the theory. Furthermore, based on this model, the effects of impingement angle, jet velocity profile, Weber number, and Reynolds number on sheet characteristics, such as sheet shape, thickness, and velocity distribution, were investigated.
