横纹槽管束在不同支承结构下的传热及流阻性能试验
AN EXPERIMENTAL INVESTIGATON FOR HEAT TRANSFER AND FLOW FRICTION CHARACTERISTICS OF ANNULAR GROOVED TUBE BUNDLES
【摘要】 <正>横纹槽管是苏联60年代由Mигай和Kaлинин等人开发的双面强化管(图1)。它只有边界层分离流,而无对传热作用不大却使流阻增加较多的螺旋流,故其性能明显优于螺
【Abstract】 An experimental investigation for heat transfer and flow friction characteristics of annular grooved tube bundles under six different shell support conditions is reported in this paper. A comparative evaluation based on the experimental results is carried out by means of Webb’s performance evaluation criteria. It is concluded that it would be best to select support structure with the least flow friction at the shell side of annular grooved tube bundles.
