FliHy experimental facilities for studying open channel turbulent flows and heat transfer

B Freeze, M Dagher, T Sketchley, N Morley, M Abdou2002年Fusion Engineering and DesignIF 1.7出版社

AbstractThe FliHy (Flibe Hydrodynamics) facility was constructed at UCLA to study open channel turbulent flow and heat transfer of low-thermal and -electrical conductivity fluids. At present, water is used as a stimulant fluid for molten salt, e.g. Flibe. A similarity analysis matched the dimensionless parameters in the experiment with those in the ARIES-RS First Wall design. Unlike previous studies of open channel flow, the goal of the present one is to study supercritical flow regimes (Fr>1), in which the surface waves are amplified and heat transfer is enhanced due to surface renewal. The paper describes the facility and gives the results of measurements of the flow thickness and their analysis.

FliHy(フライベ水力学)施設は、UCLAにおいて、低熱伝導率・低電気伝導率流体の開水路乱流および熱伝達を研究するために建設された。現在は、溶融塩(例:フライベ)の模擬流体として水が使用されている。相似解析により、実験における無次元パラメータはARIES-RS第一壁設計のものと一致させられた。開水路流れに関する従来の研究とは異なり、本研究の目的は、表面波が増幅され、表面更新により熱伝達が促進される超臨界流れ領域(Fr>1)を研究することである。本論文では、この施設について説明し、流れの厚さの測定結果とその解析を示す。
