The rheology of benzene and nanofluids based on it with spherical particles has been studied by the method of nonequilibrium molecular dynamics. As the shear rate increases, all these fluids become pseudoplastic. Critical values of the shear rates of rheology change and their dependence on the concentration of nanoparticles, their size and material are established. The change in rheology is accompanied by a change in the structure of the studied fluids, which is illustrated by the evolution of the corresponding radial distribution functions. Keywords: molecular dynamics method, nanofluids, viscosity, rheology.
