Results of numerical investigations of the decay of swirl in laminar flow of a generalized Newtonian fluid in a circular pipe have been presented. The authors used water and a 0.67% Na–CMC aqueous solution as the working medium. A comparative analysis has been made of the obtained results and the results of other authors. Equations describing the dependence of the intensity of flow swirl on the dimensionless axial coordinate have been proposed.
