P. Atten et al., THE ROLE OF CONDUCTION IN ELECTRORHEOLOGICAL FLUIDS - FROM INTERACTION BETWEEN PARTICLES TO STRUCTURATION OF SUSPENSIONS, Journal of electrostatics, 40-1, 1997, pp. 3-12
After a brief description of the electrorheological (ER) fluids and of
their properties, we recall the basic physical processes responsible
for the electrically induced interactions between particles. We then g
ive a short review of recent work on ER effect in the case of D.C. app
lied fields where the conduction properties of the components play the
major role. The conduction model for estimating the attraction force
between two spheres is presented along with some experimental results.
Finally we shortly address problems raised by the ER fluids such as t
he prediction of their static yield stress and of their apparent visco
sity.
