ABSTRACT

A power plant is one of the key infrastructures for developed countries. These plants are occasionally shut down by the intrusion of marine life (seaweed, fish, Jellyfish, shrimp, etc.), which causes serious socio-economic problems. Air bubble barrier have been used to prevent sea life from entering the power plant intake port and stopping power plants. In this study, an experimental device is developed to analyze the vertical behavior of air bubbles. The empirical equations are presented by measuring the rising speed of air bubble by water depth according to the amount of air injection. The proposed empirical equations will be used as a basic tool for the design of an air bubble barrier, which is expected to contribute to secure the operational stability of power plants.
