The spray characteristics of Gas-Centered Swirl Coaxial Injector was investigated that there were different characteristics with or without gas flow. As gas flow was accelerated, the momentum of gas was transferred to the momentum of liquid in the low liquid Reynolds number. Therefore, the axial velocity of liquid was increased and the measured value was smaller than without gas flow. However, in the high momentum flux ratio, the momentum transfer hardly occurred and the results had constant values. As the recess length was increased, the mixing area of gas and liquid also was increased, the results were decreased.

The spray characteristics of Gas-Centered Swirl Coaxial Injector was investigated. There were different characteristics with or without gas flow. When gas flow was accelerated, the measure value was smaller than without gas flow. The spray angle, breakup length and film thickness were presented in accordance with the momentum flux ratio. As the momentum flux ratio and recess length increased, the measured values decreased.
