Investigation of stability and secondary flows in rotating spherical layers at arbitrary Rossby numbers
Abstract
Photographic flow visualization was performed to study the stability of a spherical Couette flow in a layer formed between concentric rotating spheres (where the outer sphere rotates or where both spheres rotate); the shells are made of plastic and the working fluids are mineral oil, a benzenesolution of mineral oil and benzene. It is found that, depending upon the values of the similarity parameters of the problem, the Reynolds number, the relative thickness of the layer, and Rossby numbers, the nature and shape of the flows excited in the spherical layer are very diverse; the flows can be axisymmetric and threedimensional, steady and wavelike, and can be concentrated in the equatorial region or in the thin cylindrical layer.
