The Japan Atomic Energy Agency (JAEA) has been conducting simulation design study on process gas reactor for one of the heat utilization system components development of HTGR (High Temperature Gas-cooled Reactor). But, numerical analysis of gas-mixing turbulent flow in reactor is difficult. Also, it is lack of experimental results for verification of the numerical analysis model featured this flow field. Therefore, in order to obtain the experimental data to verify this analysis model, it was carried out that an experimental study in bent rectangular duct with flow control door by using PIV (Particle Image Velocimetry). As a result of this study, it was obtained representative velocity distribution data at the vertical cross section of the duct.
