Design and Analysis of Venturi Microbubble Generator Using Computational Fluid Dynamics

The necessity for dissolved oxygen in water is crucial the survival and growth of aquatic organisms, particularly tilapia. Seventy-five percent tilapia will die if there insufficient water. This work seeks to develop a venturi bubble-generating technique combat scarcity A floating pump with capacity 12 m<sup>3</sup>/hour was selected as medium distributing generating vacuum pressure draw air mixing flow venturi. Ansys Fluent used model piping systems. system modeled single-phase (water) at steady state, whereas multiphase (air water) under transient situations. simulation findings revealed that drop 90-degree elbow much greater (27.17 kPa) than 45-degree (16.53 kPa). 1-inch input diameter produced bubbles an average 105 µm, ½ inch bubble generator 83 µm. Owing numerous advantages adopting six-outlet venturi, this design recommended pumps m<sup>3</sup>/h.
