Use of Fiber Optics for Bubble Studies

Abstract:

Air-water flows are of importance for all the areas related to fluid mechanics. Especially, although kinematic investigations of the multi-phase flows have been conducted for a long time, velocity measurements are still considered as a very challenging part. This study introduces an imaging technique applying shadowgraphy and coupled fiber optic probes for velocity measurements of air bubbles. The fiber optic probes apply optical fibers to the well-known intrusive phase detection probe with a shape to reduce flow disturbance. The present method is used for bubble plume measurements and obtained velocity result is discussed. Finally, the velocities are compared to examine the reliability of the methods.
