A combined Analytical Experimental and Numerical Investigation of Turbulent Air Flow Behaviour in a Rotor-Stator cavity
Résumé
The present work focuses on a turbulent flow with separated boundary layers in a rotor-stator system opened to the atmosphere at the periphery, where the pre-swirl ratio of the fluid is low. Under these conditions, the fluid in the core does not always rotate as a solid body, as expected by the solution of Batchelor (1951). The experimental, theoretical and numerical results clearly explain this phenomenon.
