Abstract

The Taylor–Couette system, describing the flow of a viscous fluid between two coaxial, independently rotating cylinders, has long served as a method for studying hydrodynamic stability, fluid pattern formation, and the transition to turbulence. Despite its conceptual simplicity, precise construction of an apparatus meant to isolate Taylor–Couette flow requires careful control of boundary conditions, rotational speeds, and geometric tolerances to accurately capture the on set and evolution of flow instabilities. In this work, we present the theory, design, and construction, of a custom-built Taylor–Couette apparatus optimized for experimental investigation of vortex dynamics. The apparatus features, independently controlled rotation rates, with theoretical functionality to explore the entire Taylor-Couette space, and rheoscopic fluid for flow visualization. Emphasis is placed on creating a versatile device, capable of clearly differentiating between the different flow regimes. Preliminary validation tests demonstrate clear observation of laminar Couette flow, on set of Taylor vortices, and progression toward wavy and turbulent states. This platform enables future quantitative studies of critical thresholds, vortex structure, and nonlinear flow transitions in one of fluid mechanics’ most historically significant geometries.
