Image Analysis Of Air-Bubble Injection (Front And Side View) Into A Turbulent Liquid Stream, Navjot Kaur

Dissertations and Theses

"This study concerns an air bubble injection experiments in a vertical upward annular channel in which a 0.4 mm hole was created to inject the air bubbles into the turbulent stream. Water was used as a testing fluid, and the experiments were performed at atmospheric pressure and room temperature. A high-speed video camera was used to capture the dynamics of the bubble formation process. Two different experimental views were used: a front view in which flow velocity was 0.80 m/s (2.68 GPM) at Reynolds number, Re=7413 and to inject air bubbles into water stream air bubble injection rate was set …
