The experimental study the of hydraulic impedance occurring during flow of the water-grain suspense in pipelines

Alexander G. Novoselov, Chebotar A.V., Gulyaeva Yu. N. , Meradzhi V.V.

Present study reviews methods for calculating dependencies for the purposes of studying the flow of non-Newtonian liquids in pipelines and proposes two ways to evaluate hydraulic resistance of the flow. Furthermore, we suggest a novel sequence for use of the rheodynamic data for engineering design of pipelines. Also, we propose hydrodynamic testing set-up to model water-thermal treatment of milled grain. We present data obtained during the study of hydraulic impendфnce of the water-grain suspensions flow in pipelines. In particular, we show dependence between the friction coefficient and the Reynolds’s number measured during flow of water-grains suspension through the studied section of a pipeline at hydro module value of 1:4 and at various temperature values.
