Abstract
Detailed measurements of turbulent quantities in the interacting wake of two cylinders have been made. The measurements comprise profiles of mean velocity, turbulent kinetic energy, Reynolds shear stress, intermittency and dissipation in the interacting wake of two equal diameter cylinders, at a number of downstream stations. The diameters of the cylinders as well as the spacing were varied. Simple formulations have been made to predict the distribution of intermittency and turbulent kinetic energy in two cylinder wakes based on measurements in single cylinder wakes. Comparison with measured profiles have proven to be satisfactory. The individual terms of the turbulent kinetic energy equation have been evaluated to present the TKE balance. The measurements were taken at 87 fps giving a Reynolds number range of from 11000 to 22000 (based on the diameter of a single cylinder).
