摘要：

An online and non-invasive ultrasound Doppler based rheometric method is proposed to measure the flow parameters in a dilute liquid-solid two-phase flow and analyze its rheological behaviours. The flow rate is obtained by integrating the ultrasound Doppler velocity profiles through annuluses formed across the cross-sectional area of the pipe while the pressure drop is calculated by choosing suitable models that captures the working conditions of quasi-homogeneous and heterogeneous dilute liquid-solid flows. Wall shear rate and wall shear stress are obtained from the above measurements with the rheological measurement models established. An experimental platform is built to form polystyrene-water and sand-water liquid-solid two-phase fluids for tests. The proposed method has mean absolute errors of 2.53% and 3.49% in flow rate measurement and 3.67% and 5.87% in pressure measurement for polystyrene-water and sand-water fluids, respectively. The experimental results have shown that the rheological characteristics of both fluids fit well with the power law fluid model.
