Curved Flow Flow Accelerated Erosion Mass Transfer Nuclear Power Plant Orifice Pipe-wall Thinning Stereo PIV Swirling Flow
Abstract The velocity field behind an orifice in a circular pipe is studied by PIV measurement u nder the influence of curved swirling flow to elucidate the asymmetric pipe-wall thinning pheno menon behind an orifice. The experiment is carried out in a closed water tunnel at Reynolds numb er Re = 19,000. The stereo PIV measurement of the cross-sectional velocity field in a pipe flow indicates that the flow reattachment occurs on one side of the pipe flow irrespective of the ori fice bias. This is due to th...

linac NDT onsite inspection pipe wall thinning X-band
Our portable X-band (9.3GHz) 950KeV linac has been successfully upgraded. The problems of RF power oscillation , beam current oscillation and reduction and finally lack of X-ray intensity were solved by replacing the axia l coupling cavities with the side-coupled ones. Designed X-ray dose rate of 0.05 Sv/min@lm is going to be achi eved. Length of the accelerating tube is reduced to less than 25 cm. X-ray source part with the local radiation shielding is connected by the flexible waveguide with the box of t...

360-degree camera Patrol system Simultaneous Localization and Mapping
From a viewpoint of safe operation and the improvement in an operating ratio of equipment, Efficient maintenance engineering and inspection work is needed. Therefore, we developed a patrol system using 360-degree camera and self-localization technology. A 360-degree camera which can photo the image of all the directions was used for this system. It can record the spherical image of an inspection worker, and enables the inspection image of the direction to need. Moreover, early detection of change of an on-s...
