Библиографическое описание: NUMERICAL STUDY OF NON-NEWTONIAN FLOWS WITH SOLID PARTICLES IN PIPES AND ANNULAR CHANELS : научное издание / A. Shebelev, A. Gavrilov, A. Minakov. - Текст : непосредственный // Eurasian Journal of Mathematical and Computer Applications. - 2025. - Т. 13, № 2. - С. 83-89. - ISSN 2306-6172. - ISSN 2308-9822, DOI 10.32523/2306-6172-2025-13-2-83-89.
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 a drilling 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>
