Flow control of Frictional drag reduction by injected bubbles

Purpose of Research

Frictional Drag Reduction by Injected Bubbles

We are making continuing effort to improve Particle Image Velocimetry as applying these methods to a variety of flowfields where conventional techniques were impossible or invalid, targeting to clarify the essential flow characteristics in those configurations. Applying this method and the way of approach to solution, we select the research topics that will respond to industrial needs.

Summary of Research

New technology of measurement for multiphase flow

The research of bubble is classified Multiphase flow in fluid dynamics. Multiphase flow is research field which include solid, liquid and gas. The research of bubble oganaized liquid and gas called a gas-liquid two-phase flow. But Albert Einstein(1879-1955) is one of scientist which has interest in gas-liquid two-phase flow (Einstein, A. 1906, Effect of suspended rigid spheres on viscosity, Ann. Phys. 4, p. 289). We expect that the mechanisms of drag reduction by injected bubbles are interaction between bubbles and turbulent structures, bubble deformation, or chenge of effective viscosity.
