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.
