- ABSTRACT: As we known, unstable flows in the field of inertia due to convective acceleration and viscous friction are widely used in hydraulic systems. But in the same time, the bad studied flow of electrically conductive liquids remains under conditions when an additional effect on the flow forces with a magnetic nature arises a flow in the cross section. Essentially relevant and insufficiently studied problem is the behavior of liquids in the initial section, which has the following forms. Shown that in the absence of inertia forces from convective acceleration (in the Stokes flow) the velocity diagram depends only on the rheological properties of the fluid. In this work we identifies the conditions under which the magnetic field contributes to the inhibition of the flow in the channel; Cases where the fluid exhibits an anomaly are considered and data on the determination of the velocity and stress fields are obtained. Physical modeling was carried out using capillary viscometers of various diameters. Rheological studies have shown that the fluids which were in use can be described by the laws of Newton, Ostwald-de-Ville and Ericksen.
