Dimensional Analysis of the Electrorheological Behavior of Milk Chocolate

  • Christopher R. Daubert

Electrorheology (ER) is concerned with the effects of electric fields on the flow properties of liquid suspensions that show an increase in apparent viscosity and a greater yield stress during exposure to electric fields. These fluids require polarizable particles suspended in an insulating (non-conducting) oil. The ER phenomenon results from the formation of microstructures of the dispersed solid phase. In other words, the field-induced microstructures attempt to span the fluid gap, causing reduced fluidity.
