摘要：
The Coriolis mass flowmeter (CMF) has the advantages of a simple structure and direct measurement of fluid mass flow rate. This paper numerically simulates the fluid-structure interaction (FSI) of a straight tube CMF based on the monolithic coupling methods of hydrodynamics and structural mechanics with liquid hydrogen (LH2) as the working fluid. The simulated time lag for the CMF with water is firstly compared with the results from the published experiment and the iterative partitioned coupling method to validate the model. The com-parison shows that the results of the monolithic coupling are closer to the experimental results. Then the monolithic coupling method is used to analyze the FSI characteristics of the CMF with LH2. And the general flow -induced vibration results with LH2 are presented for the straight tube CMF, including the dry and wet vibration modes. The velocity and the detector positions on the time lag are specially discussed. The results reveal the FSI characteristics of the straight tube CMF with LH2.
