| Abstract: | Wet gas flow is a subset of gas–liquid two-phase flow, and wet gas metering is gaining considerable attention due to its importance in the nuclear, oil and gas industry. Wet gas meter based on slotted orifice and swirlmeter combination in series was designed and investigated. A wet gas measurement model with the simultaneous equations from the two flowmeters' correlations has been established, and then an iterative solution algorithm is given. The novel proposed approach predicts the gas mass flow rate relative errors within ±6% from 89.2% tested samples, and the gas mass flow rate relative errors within ±20% from all tested samples, which is accepted for many wet gas applications. Therefore, it implies that the proposed wet gas metering technique may be used to meter both gas and liquid flow rates for wet gas flow at the Lockhart Martinelli parameter X≤0.12. |
