ترجمة الملخص

The study of rotational flows is important research study which can be observed in rotor-stator cavity have begun since 1951 with the emblematic work of Batchelor. But very recent studies provided new and completely different approach and opened the door to scientific research in this field. The importance of those studies, the lack of completed data for the development of analytical models represent the flow in the cavity with superimposed radial flow, which enables us to determine the forces on the discs of turbomachines and identify the physical characteristics of the turbulent flow outside the boundary layers separated with central core. But recent studies have shown the importance of flow turbulence on the central core flow and consequently to complete the experimental approach with numerical modelling and find the better way to represent the Reynolds stress tensor with the dimensionless flow parameters as well as with radial and axially cylindrical coordinates. The study is conducted using a specialized commercial codes of CFD and the results are compared with experimental and analytical results that have been carried out from the literature. These results, which brought out lighting on the nature of the flow between the two boundary layers in this cavity led the researchers to introduce radical changes on the analytical models developed using only from the experimental data. And once more this work highlighted the importance of the role of pre-swirl ratio of the flow characteristics inside the cavity. The researcher concludes that the experimental data base, using the LDA or the PIV, should be considered as soon as possible.
