Edit1978 New Fundamental Considerations on Mixing in Laminar Flow
Lewis Erwin, Assistant Professor Mechanical Engineering - University of Wisconsin Madison
EditIntroduction
Mixing is one of the most common operations performed by man. From mixing fuel and air for combustion to mixing sugar in tea for taste, the fundamental necessity for taking segregated materials and creating uniform mixtures is the same. In most mixing operations, turbulent flow of a fluid is the primary mechanism of achieving mixing. However, there are many processes where the viscosities of materials are so high that it is not possible to attain turbulent flow. The most familiar experience in this type of mixing is in the kneading of bread where much work is necessary to make the mass of dough homogeneous. Mixing problems where turbulent flow is not possible arise in areas such as the processing of foods, cosmetics, glass, rubber, and plastics. This is the area of current interest.
