液相流動床中に埋設された水平管群の熱伝達 : 第2報,碁盤目配列を含む基本的管配列の熱伝達(熱工学,内燃機関,動力など)  [in Japanese] Heat Transfer on Tube Bundles Embedded Horizontally in a Liquid-Fluidized Bed : 2nd Report, On Tube Bundles of Fundamental Layouts Including In-Line Layouts(Thermal Engineering)  [in Japanese]

Heat transfer coefficients were measured on tube bundles of fundamental layouts including inline layouts embedded horizontally in a liquid-fluidized bed. Tested tube layouts were single tubes, transversal single tube rows, longitudinal single tube rows and in line arranged tube bundles. A total of 7 kinds of particles were used. Comparisons of the experimental data showed a good agreement with the heat transfer correlation developed for staggered layouts, when the average liquid velocity through each tube bundle was used as the reference velocity for the particle Reynolds number. Distribution of local heat transfer coefficient was also investigated around tubes.
