Аннотация: <jats:p>The paper presents the results of modeling non-Newtonian flows with solid particles using the single-fluid model proposed by the authors. The proposed model was verified and validated on problems of steady-state turbulent flow of a non-Nontonian fluid with heavy particles in a horizontal pipe and an annular channel. Using aПоказать полностьюdrilling fluid modified with carbon nanotubes as an example, the influence of fluid rheology on the reliability of modeling was studied. By comparison with experimental data, DNS-DEM modelling data and calculations performed using the two-fluid model of granular media, it is shown that the proposed model can satisfactorily predict the distribution of particle concentration and pressure drop in the channels.</jats:p>
