摘要:
在相同管长,相同管径及相同实验工况下,对内置螺旋叶片转子换热管和光管进行换热实验,研究了该两种换热管的传热性能,并对比分析实验后两种换热管的污垢沉积厚度, 最后利用FLUENT软件研究内置螺旋叶片转子换热管和光管的z=290 mm、z=710 mm两处截面的污垢分布.结果显示:在同样的条件下,内置螺旋叶片转子换热管比光管具有更好的传热性能,前者的传热系数大约是后者的1.3倍左右;相对于光管螺旋叶片转子换热管的传热效果趋于稳定;螺旋叶片的换热管内部污垢沉积分布均匀，并且叶片转子两端区域的污垢沉积分布大致一样;光管内整体污垢分布不太均匀,同一截面处顶端污垢厚度明显大于底端;从光管的入口到光管的出口,颗粒的污垢沉积厚度逐渐增大.内置螺旋叶片转子换热管相对于光管具有良好的抗垢特性，提高了传热效率.
Abstract:
In the same tube length, the same diameter and the same experimental conditions，the heattransfer experiment of a builtin helical blade rotor tube and a plain tube was conducted to study the heattransfer performance of the two kinds of tubes, and the dirt deposition thickness of the two kinds of tubes was comparatively analyzed, finally, the FLUENT software was used to study the dirt distribution of the builtin helical blade rotor tube and the plain tube at the crosssection of z=290mm and z=710mm. The results show that the builtin helical blade rotor tube has better heattransfer performances than the plain tube in the same conditions，and the heattransfer coefficient of the former is about 1.3 times of the latter；the heattransfer performance of the builtin helical blade rotor tube is more stable than that of the plain tube’s. The dirt inside the builtin helical blade rotor tube is evenly distributed，and the dirt distribution in both ends of it is basically the same; the dirt inside the plain tube is unevenly distributed, and the dirt deposition thickness in the top is obviously bigger than that in the bottom; the dirt deposition thickness of particles becomes larger；from the entrance to the export of the plain tube. The builtin helical blade rotor tube has better antifouling characteristics than the plain tube, improving the heattransferefficiency.
