Jet velocity, impingement angle, and jet momentum ratio were varied to provide a wide range of jet operating conditions. Results indicate that the overall spray patterns vary dramatically with the change of jet velocity. The impingement angle has a great influence on the instability characteristics of the impact wave, and there exists an excessive impingement angle which may lead to the backflow of the liquid fuel, thus causing serious wall ablation when an impinging-type injector is used in liquid rocket engine combustors. Furthermore, the liquid sheet deviates from the symmetry axis when the velocities of the two jets are not the same, leading to a bow-shaped liquid sheet. %8 2017-12-28
