This image shows the velocity magnitude in a plane below an impeller. The fluid is viscous and the Reynolds number is approximately 10. The calculations were performed using a sliding mesh model. Inc. This image shows streaklines in a stirred vessel. Solids suspension, the mixing of a solid into a liquid, is a common occurrence in the process industries.
Examples are crystallization, and leaching of minerals in mining applications.
This image shows the solids distribution in a stirred tank, with a single impeller drawing 3.5 kW on the left, and with three impellers drawing a total of 2.3 kW on the right. The solids are more uniformly suspended with the three impeller system, despite the lower power draw.
