Local resistance of fluid flow across sudden contraction in small channels

Frontiers in Energy 2010, Volume 4, Issue 2,   Pages 149-154 doi: 10.1007/s11708-009-0060-7

Abstract: The pressure drop caused by flow area contraction in microchannels has been experimentally studied in this paper using the tiny gap pressure measurement method. The working fluid was deionized water at room temperature at near-atmospheric pressure. Three test sections with area ratios of 0.284 and 0.274 and at different tube diameter sizes were used. The experimental results show that the abrupt contraction coefficient decreases with the Reynolds number increasing, and it is much higher than that of conventional tubes in laminar flow. The widely-applied correlation =0.5(1−) could not predict the contraction coefficient of turbulent flow in the micro tubes. The decreases as the tube diameter increases. The transition from laminar to turbulent flow is not obvious when the diameter of the small tube is 0.32mm.

Abstract:

Understanding the transport resistance of water molecules in polyamide (PA) reverse osmosis (RO) membranesIn this work, we use molecular simulation to calculate the total transport resistance by dividing itThe interior resistance is dependent on the thickness of the PA layer, while the interfacial resistanceThis implies that there is a risk of inaccuracy when using the typical method to estimate the transportresistance of RO membranes, as this method involves simply multiplying the total transport resistance
