The present experimental work is concerned with the study of effervescent atomisation, a two-phase gas-liquid spray generation technique that offers many advantages over conventional atomisers. This study shows the advantage of streamlined aerator design over flat-end aerator type with respect to formation of gas void in the aerator wake in the interior of an inside-out type of effervescent atomizer. The experiments are performed employing high-speed shadowgraphy visualizations. It is observed that in the conventional flat-end type of aerator design the formation of gas void is undesirable and leads to spray characterized by instabilities, causing fluctuating spray properties. The existence of gas void also prevents the formation of bubbly flow inside the effervescent atomizer which is actually preferred in these types of atomizers to enable stable spray generation and fine atomization. The formation and existence of gas void is found to be a result of aerator bluff body recirculation and gas phase buoyancy effects. Four different streamlined aerator designs with tips in the shape of circular arc, circular arc/conical hybrid, conical and DARPA SUBOFF afterbody design (which is common in the conventional ship designs) are evaluated to determine the best among them with respect to mitigating the unwanted gas-void in the interior of an effervescent atomizer. These are evaluated with respect to ability to produce bubbly flow over comparatively large operating range and the ability to impart minimum wake (of aerator body) effect. It is concluded, upon careful experimental observations, that DARPA SUBOFF afterbody design is the best among the streamlined aerator designs.
