Microscopic particle-image velocimetry (microPIV) measurements are made in the streamwise–wallnormal plane of a 536 lm capillary at Re = 4,500 to study the statistical and structural features of wall turbulence at the microscale. Single-point velocity statistics, including the mean velocity profile, the root-mean-square streamwise and wall-normal velocities, and the Reynolds shear stress profile, agree well with established direct numerical simulations of turbulence in the same geometry at Re… CONTINUE READING
