Mixing Design Considerations For mixing for solids suspension, consider the following factors: Tank Dimensions Baffles The impeller: material, shape Settling velocity of solids: specific gravity, size, etc. Solids concentration Temperature Difficult to quantity; a highly empirical process. Tank baffles are devices added to the inside of a vessel near the vessel wall. Their main purpose is to reduce the tangential velocity component of the total velocity field imparted on the fluid by a mixing impeller. This results in top to bottom fluid turnover within the vessel, which is essential for most mixing applications.
