Abstract

In this research, a new bubble generator to produce fine bubbles was designed and manufactured through the interaction between a strong swirl and coanda flow at the edge of an exit nozzle, a larger bubble could be breakdown into fin microbubbles. A significant vacuum pressure was created at the throat of the exit nozzle to induce the atmospheric air required for bubbles generation process replacing high cost compressed air systems. This study covered coanda radius (0 and 20 mm), water flow rates 21.4 l/min and air flow rates 0.1 to 0.9 l/min. The results indicate, fine average diameter range between 64.3 to 87.6 µm depending on air flow rates and coanda radius. Bubble diameter decreases with increasing coanda radius and reducing the induced air flow rate.
