Abstract
Ejection of microbubble within water has been investigated for several years as a method to achieve pipe friction loss reduction. However, the physical mechanism of this phenomenon is not yet understood. Therefore, the purpose of our study is to understand the reduction mechanism. We researched pipe friction loss reduction by the experiment, which was constructed by a circular pipe. Adherence of bubbles to the pipe wall had an effect on pipe friction loss. In the case of void fraction 0.1% ± 0.02%, microbubble influenced pipe friction loss reduction. Moreover, turbulence intensity calculated using Particle Image Velocimetry (PIV) measurement technic. In the result, turbulence intensity decreased in the case of the water injecting microbubble. As the result, we thought that microbubble controlled turbulence intensity of circular tube flow.
