dc.description.abstract | LDV measurements of the all velocity components were carried out in an open channel flowover hydraulically rough surface of which roughness Reynolds number was 200. Using two setsof LDV, three velocity components were measured simultaneously. Secondary currents weremeasured, and these data showed the existence of depth-scale longitudinal eddies. Profiles ofthe Reynolds stress, turbulent kinetic energy, turbulence-kinetic-energy production, and theturbulence-kinetic-energy dissipation are also given. These results in an up-flow-part of longitu-dinal eddy were compared with those in a down-flow-part. The u-v and u-v-w quadrants method, and the VITA variance technique concerning with accelerations and retardations of u wasemployed to detect the three dimensional turbulent structure. | en |
