Abstract
In order to investigate spray characteristics of gas-centered swirl coaxial injectors, a phase detection optical probe is employed to obtain the spatial evolution of the drop size and velocity. From the study on the optical probe responses under various impact angles, it is demonstrated that the drop size and velocity can be measured with an uncertainty less than 15% when the probe axis remains within about
