The results of some experiments on turbulenoe management using combinations of honeycombs of different lengths and coarse and fine screens, oarried out in highly nonuniform and turbulent flows generated in a 127-mm plexiglas pipe by an upstream blower and diffuser, are presented. The performance of the devices as single manipulators and in combination was evaluated through hot-wire measurements of the mean and rms .values of the longitudinal velocities over the pipe cross section. The results show that relati vely short honeycombs, preceded by a coarse screen and followed by one or more fine screens, oan be used for effective management of highly nonuniform and turbulent flows.
