EXPERIMENTAL STUDY OF VELOCITY DISTRIBUTIONS IN THE TRANSITION REGION OF PIPES被引量:5
《Journal of Hydrodynamics》2011年第5期643-648,共6页LIU Yong-hui DU Guang-sheng LIU Li-ping SHAO Zhu-feng ZHAI Cheng-yuan 
supported by the National Natural Science Foundation of China (Grant Nos. 10972123,10802042);the Natural Science Foundation of Shandong Province (Grant No.Y2007A04)
The accuracy of an ultrasonic flowmeter meaurement depends on the profile-linear average velocity. But this velocity in the transition region is not available at the present. In this article, the velocity in the trans...

A STUDY ON THE FLOW IN HELICAL ELLIPTICAL PIPES WITH GALERKIN METHOD
《Journal of Hydrodynamics》2006年第1期70-76,共7页MA Jian-feng SHEN Xin-rong ZHANG Ben-zhao ZHANG Ming-kan 
Project supported by the National Natural Science Foundation of China (Grant No :10272096)
The fully developed laminar flow in helical elliptical pipes is influenced by curvature, torsion and aspect ratio of cross-section. With the aid of the symbolic manipulation technique, the governing equations were sol...
