Abstract

The study of rotational flows is considered one of the important research fields, as these direct flows between rotating and fixed disks are analyzed. These studies began as far back as 1951 by Batchlor, but recent studies have provided new and completely different approaches, opening up a wide field of scientific research in this field.

The importance of this study lies in the lack of integrated data to develop analytical models for flow equations in cavities subject to forced flow. This helps us to determine the forces acting on rotating discs in water machines and to understand the physical properties of flow outside the boundary layers For turbulent flow, studies have been directed towards evaluating the intensity of turbulence in the central core, and Reynolds components have been related to the characteristic non-dimensional values of the flow and the spatial coordinates radially and axially. The study was conducted using commercial software specialized in modeling fluid flow, and the experimental and analytical results were compared with references and previous studies.

These readings added to our understanding of the nature of the flow between the two boundary layers in this cavity, and led to radical modifications to the analytical laws based on the experimental approach. The study showed the importance of non-dimensional circumferential angular velocity in shaping the flow inside the cavity.
