Étude de l'écoulement laminaire de deux liquides non miscibles entre deux disques coaxiaux tournant en sens contraires (Study of laminar flow of two immiscible liquids between two coaxial discs rotating in opposite sense) (Q1061573)

This paper is concerned with a theoretical study of the stationary laminar flow of two immiscible liquids between two disks rotating in opposite sense. The solution is an exact solution of the complete Navier- Stokes equations belonging to the class of similar solutions of flows between rotating coaxial disks. An approximate analytical form of this solution is given for low values of the rotation Reynolds number and numerical results have been performed for higher values of this parameter. Detailed results are discussed for relative values of fluids densities and viscosities.
