概要

• 論文の詳細を見る

• In this second report, we investigate the relation between the turbulent diffusion of a bubble and eddy diffusivity of heat in the core of a fully developed pipe flow. As a result, it is found that the diffusivity of bubbles is smaller than the eddy diffusivity of heat, and can be divided into three regions, corresponding to the distribution of terminal velocities of bubbles in water against the size of bubbles.
