Unsteady Flow of Rheologically Complex Fluids in Cylindrical Pipes

In this article, we have studied the process of transition from the non-stationary state to the stationary state of the mixture formed by adding a Newtonian fluid to a rheologically complex fluid in a cylindrical tube. We used the analytical method. The advantage of this type of fluid flow research is that it allows for a more comprehensive study of fluid motion. Among the obtained results, it is necessary to note new results that are of great importance in revealing the state of the physical phenomenon. The graphs of the results were made using Matlab mathematical software. For a better understanding of the physical properties of some of the obtained results, their graphical representation is shown. These results are effective for further development of unsteady flow of rheologically complex fluids in cylindrical pipes.
