An experimental method to generate stable, controllable and periodic gas-in-diesel compound drops by coaxial compound jets is presented. The compound jet can be categorized into bubbling and jetting regimes in the upstream or into bubbling and compound drop regimes in the downstream. The characteristics of a compound jet nozzle strongly depend on the actual sizes of the needles and the flowrates. According to experimental results, steady and periodical compound drops could be produced for Weber number less than 7 and velocity ratio within 0.2 ∼ 0.45. As the outer liquid velocity increases, the compound drop generation frequency goes down. In the compound drop regime, the satellite grows with increasing velocity ratio.
