Macro Level Mixing

Physical Processing

Physical Processing illustrates the physical degree of uniformity in mixing. This degree of uniformity can often be seen with the naked eye or be measured by a physical technique. This is why it is described as a macro level process.

Click on any of the buttons in this table to get some examples of processes that are affected by mixing on the macro level.

Physical Processing
Macro - level

Pumping - Flow Patterns Fluid Motion
Blending - Mixing Times Miscible Liquids
Emulsification - Dispersion Liquid - Liquid
Suspension - Solids Distribution Liquid - Solid
Dispersion - Flooding - Boiling Liquid - Gas
Combinations of the above Liquid - Solid - Gas
