The Structure of Turbulence Measured in a Relaxing Boundary Layer

  • U. R. Müller
Conference paper


The experiments /1, 2/ studied the interaction of a turbulent boundary layer and a cylinder wake, and documented the relaxation towards flat-plate conditions by measured mean velocities and some components of the Reynolds stress tensor. The more recent investigation /3/ continued that work. By measuring all components of the mean velocity vector and those of the second and third order tensors of the fluctuations, results of sufficient detail were provided for analysing the balances of the Reynolds stresses \(\overline {{u_i}{u_j}}\) according to the transport equations. The nonmeasurable terms were derived as closing entries to the balances. In /4/ the data have already been used for testing a computational method employing the three-equation Reynolds stress model of /5/.
