Abstract
The particle concentration dependence of the dynamic viscosity of various m ono- and double-layer sterically stabilized magnetic fluids was investigate d in the absence of an external magnetic field. Fits of the relative viscos ity data to various approximating relationships show that the flow properti es are influenced by chemical composition details, but do not depend signif icantly on dipolar interactions between particles.
