Simulation Study of Gas Flowing of Internal Structure of Ultrasonic Gas Meter
Abstract: Gas fluid dynamics of both an originally internal structure (SX structure) and a new design (QJ structure) of ultrasonic gas meter are simulated by CFX of ANSYS. Results of gas flowing velocity at typical flow points are calculated and analyzed. Gas velocity of the whole inside, the XY axis cross plane and the center part of XY axis cross plane where ultrasonic wave passes through of both the two structures is obtained. The simulation results reveal almost the same performance of gas flowing in both the SX structure and the QJ structure. Further analysis shows that comparably worse flowing performance is obtained by the QJ structure than that obtained by SX structure for requirements of real product design. Otherwise, gas fluid of the key part where ultrasonic wave passes through is in high speed; however it is more uniform and more stable than that of the whole inside or that of the XY axis cross plane, which is advantageous to accurate measurement of gas flowing velocity.
