Abstract

The turbulent flow inside contra-rotating disk cavity was numerically studied based on the finite volume method. The flow structure and its transition characteristics inside a contra-rotating were studied. The flow structure varies with the angular velocity ratio Γ of the slower disk to that of the faster one. For Γ=-1, the Stewartson-type flow occurs throughout the domain. For Γ=0, the Batchelor-type flow occurs throughout the flow region. The stagnation streamlines originating from the stagnation point are formed for-1<Γ<0, and batchelor-type flow occurs radially outward of the stagnation point with Stewartson-type flow radially inward. The stagnation point moves radially outward as Γ is reduced.
