Twente Turbulent Taylor-Couette System (T3C)
Taylor-Couette (TC), the flow between two rotating cylinders is a model system for research on turbulence. As such it is very similar to the Rayleigh-Benard convection (RBC), i.e., the flow between horizontal parallel plates, driven by a thermal gradient. While in TC angular momentum is transported from the inner to the outer cylinder, in RBC thermal energy is transported from the bottom to the top. In this proposal, we ask for measurement time at the Twente Turbulent Taylor-Couette facility (T$$^{3}$$C) to study the influence of rough boundaries on the angular momentum transport. Such boundary will alter the adjacent fluid layers and thus alter the global transport of angular momentum. These measurements will be compared with similar measurements in RBC.
