An experimental study was performed to improve atomization and to control dispersion of spray (water) which was ejected from hole type nozzles (main nozzles). Hence secondary liquid (water) was injected into the main liquid flow at the hole entrance of the main nozzle from an internal nozzle which was incorporated into the main nozzle, when poor atomization is caused by the phenomenon of hydraulic flip in a nozzle hole. Breakup length increases with increasing flow rate of secondary liquid up to maximum value, and then decreases, so that the breakup length approaches minimum value and significant improvement is achieved, when the internal nozzle is located at the centerline of the main nozzle. Similar trends are observed in offset positions of the internal nozzle from the centerline of the main nozzle. The minimum value of breakup length is hardly influenced by the offset position while the flow rate, when the breakup length reaches maximum value, are affected by the offset position.
