The MUFFINS project assembles a multidisciplinary team from Newcastle University, Imperial College London, University of Glasgow, industrial partners including BP, Chevron, TOTAL and Forsys Subsea, who are members of the Transient Multiphase Flow and Flow Assurance Consortium, Wood Group, Xodus Group, Orcina and TNO in the Netherlands, and an academic partner, the National University of Singapore, to develop the next generation of pioneering technologies and cost-efficient tools for the safe, reliable and real-life designs of subsea systems (pipelines, risers, jumpers and manifolds) transporting multiphase hydrocarbon liquid-gas flows. This world-leading academia-industry collaboration will be the first of its kind to strengthen the UK international competitiveness in multiphase flow designs for offshore oil and gas applications. The proposed framework will specifically address fundamental and practical challenges in areas of internal multiphase flow-induced vibration (MFIV), in combination with external flow vortex-induced vibration (VIV), whose fatigue damage effects due to complicated fluid-structure interaction mechanisms can be catastrophic and result in costly production downtime. From a practical viewpoint, liquid-gas slug flows induced by the pipe geometry, seabed topography or thermo-physic-hydrodynamic instability, are common and problematical. Such flows have a highly complex hydrodynamic nature as the different mechanical properties of the deformable and compressible phases cause spatial and temporal variability in the combination and interaction of the interfaces. Subsea layout architecture, operational lifetime and environmental conditions can all affect the flow-pipe interaction patterns. Nevertheless, reliable practical guidelines and systematic frameworks for the response, stress and fatigue assessment of subsea structures undergoing MFIV are lacking. Greater complexities and unknowns arise when designing these structures subject to combined MFIV-VIV. Through an integrated programme combining modelling, simulation and experiment, high-fidelity three-dimensional computational fluid dynamics will be performed and a hierarchy of innovative and cost-efficient reduced-order models will be developed to capture vital multiple MFIV and VIV effects, providing significant insights into detailed flow features and fluid-structure coupling phenomena. Validation, verification, uncertainty and reliability analyses will be carried out by comparing numerical results with experimental tests and industrial data to improve confidence in identifying the likelihood of fatigue failure and safety risks. Computationally-efficient tools and open-source codes will be advanced and utilised by industry and worldwide researchers. The project will minimise uncertainties in MFIV-VIV predictions associated with multi-scale multi-physics fluid-elastic solid interactions, ultimately delivering improved design optimisation and control of the most efficient multiphase flow features. The UK oil and gas industry has been at the heart of the UK prosperity for five decades but has faced significant challenges recently. In October 2016, the UK Government founded the Oil & Gas Authority to safeguard collaboration, maximise resource recovery from the UK Continental Shelf, and maintain the UK competitiveness with future investments. In alignment with these strategies, the MUFFINS project will deliver the maximum benefits to and security of global oil and gas energy by means of cutting-edge technologies, cost-efficient tools and recommended guidelines to significantly improve the integrity, reliability and safety of subsea systems transporting multiphase flows. The project will upskill the next-generation engineers and scientists in the oil and gas sector. The technical know-how and deliverables will lead to a transformative improvement in structural designs and reduction of environmental impacts, operational and maintenance costs.

MUFFINS项目汇集了来自纽卡斯尔大学、伦敦帝国理工学院、格拉斯哥大学的多学科团队，包括BP、雪佛龙、道达尔和Forsys Subsea在内的工业合作伙伴，他们是瞬态多相流和流量保证联盟的成员，伍德集团、Xodus集团、荷兰的Orcina和TNO，以及学术合作伙伴新加坡国立大学。开发下一代先进技术和具有成本效益的工具，用于安全、可靠和实际设计输送多相碳氢化合物液-气流的海底系统（管道、管线、跨接管和管汇）。这一世界领先的海洋石油行业合作将是第一次加强英国在海上石油和天然气应用多相流设计方面的国际竞争力。拟议的框架将专门解决内部多相流致振动（MFIV）领域的基本和实际挑战，与外部流涡致振动（VIV）相结合，由于复杂的流体-结构相互作用机制，其疲劳损伤效应可能是灾难性的，并导致昂贵的生产停机时间。从实际应用的角度来看，由管道几何形状、海底地形或热-水-流体动力不稳定性引起的液-气段塞流是常见的和有问题的。这种流动具有高度复杂的流体动力学性质，因为可变形相和可压缩相的不同机械性质导致界面的组合和相互作用的空间和时间变化。水下布置结构、运行寿命和环境条件都会影响流管相互作用模式。然而，缺乏可靠的实用指南和系统框架的响应，应力和疲劳评估的海底结构进行MFIV。当设计这些结构时，会出现更大的复杂性和未知性，这些结构会受到组合MFIV-VIV的影响。通过结合建模、模拟和实验的综合方案，将进行高保真三维计算流体动力学，并将开发一系列创新和具有成本效益的降阶模型，以捕捉重要的多重MFIV和VIV效应，为详细的流动特征和流体-结构耦合现象提供重要的见解。将通过将数值结果与实验测试和工业数据进行比较来进行验证、验证、不确定性和可靠性分析，以提高识别疲劳失效和安全风险的可能性的信心。计算效率高的工具和开源代码将被行业和全球研究人员所利用。该项目将最大限度地减少与多尺度多物理场流体-弹性固体相互作用相关的MFIV-VIV预测的不确定性，最终实现最有效的多相流特性的改进设计优化和控制。50年来，英国石油和天然气行业一直是英国繁荣的核心，但最近面临着重大挑战。2016年10月，英国政府成立了石油和天然气管理局，以保障合作，最大限度地提高英国大陆架的资源回收率，并通过未来的投资保持英国的竞争力。根据这些战略，MUFFINS项目将通过尖端技术，具有成本效益的工具和推荐的指导方针，为全球石油和天然气能源提供最大的利益和安全性，以显着提高输送多相流的海底系统的完整性，可靠性和安全性。该项目将提高石油和天然气部门的下一代工程师和科学家的技能。技术知识和交付成果将带来结构设计的变革性改进，并减少环境影响、运营和维护成本。
