| 英文摘要 | Floating wind power hydrogen production is a key breakthrough for deep-sea offshore wind development, in which gas-liquid separator is crucial for alkaline electrolysis hydrogen production system. However, the multi-degree-of-freedom motion of floating platforms significantly reduces separation efficiency and exacerbates structural vibration, leading to an increased risk of fatigue damage. This study proposes the use of a compact Tjunction pipeline as the gas-liquid separation unit to address the dynamic instability of the separation system under floating conditions. A numerical model of two-phase gas-liquid flow in T-junction separators under multi-degree-of-freedom motion was developed using the Volume of Fluid model with an additional inertial force method. The Navier-Stokes equations were adjusted for liquid sloshing via a user-defined function. The model was used to study how flow rate, inlet gas fraction, and splitting ratio affect the separation efficiency of hydrogen gas and a 30 % KOH electrolyte solution in a T-junction separator. Results indicate that pitching excitation has the most significant impact on the gas-liquid interface within the separator. At a pitching excitation period of 4s, the instantaneous separation efficiency fluctuates by about 70 %. However, rolling and heaving excitations mainly affect the separator initially, after which the separation efficiency stabilizes around 96 %. |
