Abstract
This study deals with rising behavior of solidified oil particles in liquids. We measured rising velocity and drag coefficient of the particles. The measured rising velocity was compared with calculated ones. The results are summarized in the followings: (1) The measured rising velocity agreed well with the calculated ones. (2) The drag coefficient of hexadecane particle is higher than those of rigid spheres. (3) The discrepancy of the drag coefficient between hexadecane particle and rigid sphere seems to be attributed to their surface conditions.
