Abstract
The homogenizer basically consists of a high-pressure plunger pump usually with triple plungers to minimize pressure fluctuations and a homogenizing valve with a narrow gap. However, the flow within the homogenizing disk part is not clarified theoretically. If the flow pattern within the disk part could be solved, a more efficient and stabilized emulsification could be carried out. The flow patterns were investigated using a CFD model of the flow in the disk part. In this paper, the influence of shape modification of the disk part was investigated in the droplet break-up action. Moreover, the influence of droplet break-up action was investigated by using two kinds of liquids.
