| 摘 要： | 本文采用污垢热阻动态监测方法,考察了冷水硬度、温度、流速及几何参数对外螺旋槽管污垢特性的影响,结果表明:螺旋槽管参数对污垢热阻有显著影响,螺距最小的螺旋槽管具有最小的污垢热阻,当螺距增大时,污垢热阻的增长未出现单调变化;温度的升高导致污垢热阻的增大,并且随温度的升高,结垢速率增大,污垢诱导期趋于消失;随着流速的增大,螺...

| Abstract: | With the dynamic monitoring apparatus,the effects of cold water hardness,temperature, velocity and tube's geometric parameter on the fouling characteristic were studied in this paper. The results indicated that the geometric parameter of spirally corrugated tubes showed great effects on fouling resistance.The shortest pitch corresponded to the smallest fouling resistance.However, the fouling resistance didn't change in the same trend with the increasing of the pitch.With the increasing of temperature the fo... |
