摘要

超声法因其穿透性好、精度高等优点成为气固两相流参数检测的一个新趋势。由于超声波在空气中衰减较大

因此

选择合适的超声波传感器对于气固两相流参数检测至关重要。通过运用有限元软件COMSOL构建超声法测量气固两相流的仿真模型

研究接收装置接收信号的大小与气固两相流固相颗粒的粒径和发射频率的关系

为实际测量选取超声波传感器提供了理论依据和指导建议。

Abstract

The ultrasonic method has become a new trend of gas-solid two phase flow parameter measurement because of its excellent penetration and high precision. Due to the large attenuation of ultrasonic wave in air

it is of great importance to select the suitable ultrasonic transducer for the parameter measurement of gas-solid two phase flow. The simulation model for gas-solid two phase flow measurement is established by the finite element software COMSOL

the relationship between signal magnitude recieved by receiving device and the solid phase particle size of gas-solid two phase flow and transmitting frequency is studied

which provides theoretical basis and guidance for choosing the ultrasonic transducer in practical measurement.
