The object of this paper is to model the complex fluid motion that is caused by the rotational motion of rotary disks. In doing so, the rotary disk occupied a normal or parallel position with respect to the fluid flow axis. Various designs of rotary bodies were also applied, with the introduction of fluid through the central opening inside the impeller of the rotating bodies and with the introduction of fluid on the outer surfaces of these impellers (surfaces limited by the largest diameters of the rotary discs). During the modeling, different initial conditions for different structures and positions of rotating bodies were adopted. For each individual stream, flow diagrams are given through a cylindrical fluid stream whose translational motion is complicated by the rotational motion of the friction disks in its flow. The results obtained give a clear picture of the disturbances and changes in the front of the fluid motion wave which can be used as a necessary experience in the design of circulating technological systems.
