Abstract
The influence of the size distribution of particles on the viscous pro perty of an electrorheological fluid has been investigated by the mole cular dynamic simulation method. The shear stress of the fluid is foun d to decrease with the increase of the variance sigma(2) of the Gaussi an distribution of the particle size, and then reach a steady value wh en sigma is larger than 0.5. This phenomenon is attributed to the infl uence of the particle size distribution on the dynamic structural evol ution in the fluid as well as the strength of the different chain-like structures formed by the particles.
