In this article presented the results of a study on improving mechanical properties composite materials based polyethylene. A composition filled with thermoplastic polymer - polyethylene modified kaolin-graphite filler is proposed, which will allow obtaining high-quality products local raw materials, simplifying material composition, and expanding their performance due to improved strength trib...

Large-eddy simulations of turbulent flow in partially filled pipes are conducted to investigate the effect secondary currents on friction factor, first- and second-order statistics large-scale motion. The method is validated first simulated profiles mean streamwise velocity, normal stresses kinetic energy (TKE) shown be good agreement with experimental data. stronger half- three-quarters full c...
