Taylor-Couette
The flow in a Taylor-Couette facility presents a Couette flow between two rotating coaxial cylinders. A turbulent flow between these presumable infinite long plates has a fully developed boundary layer. The fluid generates a shear stress on the surfaces that can be determined by measuring the torque on the inner cylinder surface. Taylor-Couette facility is an easy-to-apply and accurate measurement tool to predict the drag performance of surfaces. Different flow conditions are generated by changing the angular velocities of the inner and outer cylinders, i.e. laminar flow, Taylor-vortex flow, and turbulent flow. Velocity measurements are done by tomographic PIV to achieve a fully volumetric measurement of all three velocity components in the instantaneous flow field.
