Measurement of velocity profiles in multicomponent flows

A study of velocity profiles in a flow of a multicomponent flow of a guar polymer-based gel in a flat channel was performed. The method of planar shadow image velocimetry was used. It has been demonstrated that a flattening of the velocity profiles in the central part of the flow and an increase in the velocity gradient in the near-wall zone is observed for the cases if such components as fibers and proppant are included in the flow and their concentrations are increased.
