The Study of Gas-solid Two-phase Flow Parameter Detecting Sensor

气固两相流在工业生产与科学研究中有着广泛的应用.分析了气固两相流流体浓度与速度的测量,讨论了基于超声法气固两相流流体物理参数测量问题,提出了一种气固两相流流体流速与浓度测量传感器模型,该传感器模型具有连续测量、无放射性、实时性好等优点,为气固两相流流体测量探索新的测量仪表提供思路.

Gas - solid two phase flow measurements have a wide range of applications in the industrial produc-tion and scientific research, on the basis of discussion gas - solid two phase flow measurement of fluid concentration and the speed. The gas solid two phase flow fluid physical parameter measurement problems of fluid concentration and the speed by ultrasonic method are analyzed. A new gas solid two phase flow fluid speed and concentration measurement sensor have been proposed. This sensor has the advantages of continuous measurement, non radioac-tive ,good real - time property in the gas - solid two - phase flow measurement model, for the gas - solid flow fluid physical parameter measurement provide new ideas of measuring instruments.
