摘要
采用不同的宽型扭带在上行换热管内进行转动特性实验研究,通过对扭带转速的分析,得出了转速关联经验公式,实验结果表明宽型扭带具有在线除垢防垢的应用价值。
Experimental tests are carried out to investigate the characteristics of rotational speed in the upward flow heat transfer tube with different width twisted-tapes. By the rotational speed analysis of twisted-tapes,the correlations of rotational speed and configuration factor are obtained. The result shows the width twisted tapes have practical application value of automatically removing and resisting fouling.
