Abstract
Microbubbles have gained attention across various industries owing to their unique physical properties. Venturi-type bubble generators offer structural simplicity, low cost, and high reliability, making them widely applicable. Many studies have examined how flow conditions and geometric parameters affect bubble size and distribution. In addition, theoretical models have been developed to predict average bubble diameter under various conditions. Flow visualization has also been used to understand bubble breakup mechanisms inside the nozzle. This review summarizes recent research focusing on the effects of flow and design parameters on bubble size and predictive modeling in Venturi-type nozzle bubble generator systems.
