Abstract

The aim of this study was to investigate the characteristic of increased pressure drop in grooved straight pipes. The observation has been done at number of groove of 9, 25 and smooth pipe used as comparison. The result shows that the instantaneous pressure drop signal of grooved pipe fluctuate in small time-scale as a result the overall pressure drop increase compare to the pressure drop of smooth pipe.

带槽管道压降增大的特点
本研究的目的是探讨压降增加的特点在沟槽直管。用9槽数、25槽数和光滑管作了比较。结果表明,沟槽管的瞬时压降信号在小时间尺度上存在波动,导致整体压降比光滑管的压降增大。
