The flow of a Newtonian fluid confined between concentric double spheres, with a stationary outer sphere and an inner sphere rotating at a constant angular velocity, is referred to as spherical Couette flow (SCF). The equilibrium state of SCF is determined by the radius ratio of the inner to outer spheres, η, and the Reynolds number, Re. For η≤ 0.75, when Re exceeds the critical Reynolds number, Reᶜ, a flow characterized by high shear regions extending from the poles to the equatorial zone appears at the first transition. This transitional flow is known as the spiral state. In this study, the spiral state is visualized and analyzed at a radius ratio of η=0.5. By analyzing the brightness of the captured images, a period unique to the spiral state was confirmed, and the frequency distribution reveals the existence of two patterns with different wavenumbers. |
