Abstract

This experimental study focuses on exploiting laser Doppler velocimetry (LDV), a non-intrusive technique, for rheological characterization based on analyzing flows of Carbopol solutions at two distinct concentrations and two different temperatures within a pipe. The velocity profiles obtained using LDV and the pressure drops associated with each flow rate were exploited to establish the behavioral law of aqueous Carbopol solutions. Two approaches were used: the first was an analytical velocity model to fit the experimental profile, and the second used the first derivative of the experimental velocity profile and the pressure drops to reconstruct the flow curve. In addition, a third reference characterization was carried out using a rotary rheometer equipped with a vane geometry. This study’s three rheological characterization methods showed excellent agreement concerning the Herschel–Bulkley model. Finally, all the laws resulting from these three methods were validated using an empirical law relating to Darcy’s coefficient of friction.

管道中的粘性流体流动:利用现场激光多普勒测速仪进行流变学研究
本实验研究的重点是利用激光多普勒测速仪(LDV)这种非侵入式技术,在分析管道内两种不同浓度和两种不同温度下的Carbopol溶液流动情况的基础上,进行流变特性分析。利用 LDV 获得的速度曲线以及与每种流速相关的压降,可以确定 Carbopol 水溶液的行为规律。使用了两种方法:第一种是分析速度模型来拟合实验曲线,第二种是使用实验速度曲线的一阶导数和压降来重建流动曲线。此外,还使用配备叶片几何形状的旋转流变仪进行了第三次参考表征。这项研究的三种流变表征方法与 Herschel-Bulkley 模型非常吻合。最后,使用与达西摩擦系数有关的经验法则对这三种方法得出的所有法则进行了验证。
