|Abstract:||Taylor-Couette flow (TCF) has been a foundation of concepts of hydrodynamic stability and origins of turbulence in fluid physics and has also been useful in various fields of engineering. Alike to the concentric case, eccentric TCF also experiences transition from circular Couette flow (CCF) to Taylor vortex flow (TVF) as instability sets in with increasing Reynolds number (Re). TVF is brought about by the action of centrifugal forces, which cause the development of a secondary circulatory flow pattern in the form of toroidal vortices spaced periodically in the axial direction. The experiment was performed using a rheometer and a modified version of the apparatus to study torque characteristics of the Taylor-Couette flow between two concentric cylinders. Measurements were conducted for eccentricities ranging from 0.1 to 0.8 for each of the three radius ratios for the case of eccentric cylinders.|
