Abstract Computational fluid dynamics (CFD) models solved using ANSYS Fluent to simulate the two-phase geothermal fluid flows in production pipelines using six types of flow meters: concentric orifice, top eccentric orifice, bottom eccentric orifice, segmental orifice, Nozzle and Venturi tubes. The CFD models were then developed to predict fluid flow behaviour, including net pressure drop, velocity, turbulent kinetic energy, mass flow rate, temperature, enthalpy and entropy. The results are useful for selecting the appropriate pressure differential flow meter to measure the output of geothermal wells and their total power potential, which is of most importance to the geothermal industry.

用于测量两相地热流体流动的压差流量计的比较 CFD 建模

摘要 计算流体动力学 (CFD) 模型使用 ANSYS Fluent 求解，使用六种流量计模拟生产管道中的两相地热流体流动：同心孔、顶部偏心孔、底部偏心孔、分段孔、喷嘴和文丘里管。然后开发了 CFD 模型来预测流体流动行为，包括净压降、速度、湍流动能、质量流量、温度、焓和熵。结果可用于选择合适的压差流量计来测量地热井的输出及其总功率潜力，这对地热行业最重要。
