Fluid Motion - Macro Scale - Examples

  1. Design of pumper mixers for copper solvent extraction:  Although this is a liquid-liquid application, the main purpose of the pumper is to create enough head and flow in a closed circuit.  The dimensionless numbers for flow, head, and power are described.

  2. Flow pattern through a Line Blender doing it the wrong way (Dynamic mixing in a pipe, pipe mixer)  We show what happens when you use a Line Blender in the wrong flow direction.  It swamps the impellers.

  3. Process Intensifiers:  Optimization using CFD:  Four different styles of Line Blenders or In-Line Mixers were tested at the same conditions.  Power number, shear rates, eddy viscosity, pressure drop, flow patterns and more are looked at in great detail.  Animations of velocity are also included.
