摘　　要：氢是推动海上水、风、光、电资源清洁高效利用的理想媒介,构建深海氢能产业体系对保障能源的供应安全、实现“双碳”目标、促进能源领域企业转型升级具有重要意义。为了开展氢能等海上新能源的实验教学活动,加深学生对机械设计基础(含课程设计)、流体力学(含实验)、氢能及新型能源动力系统、氢能存储与利用等专业课程内容的掌握,该文设计了应用于海上氢气液化系统(liquid hydrogen floating production storage and offloading unit,FLH2)的浮式多孔介质通道内外流动实验装置,包括浮式通道内多孔介质流动阻力测试实验装置与浮式通道外降膜流动测试实验装置两个部分。该装置具有较好的实验教学效果,可提升学生的工程实践能力和研究海洋能源高效利用领域的创新能力,拓展学生在深海氢能储运方面的知识储备。[Objective]Offshore hydrogen gas is an ideal medium for the clean and efficient utilization of seawater,wind,light,and electricity.The development of a deep-sea hydrogen energy industry system is crucial for ensuring the security of energy supply,achieving strategic dual carbon goals,and promoting the transformation and upgrading of China’s energy enterprises.Storage and transportation of hydrogen energy is the key to offshore hydrogen energy use.Compared to gaseous hydrogen storage and transportation,liquid hydrogen storage and transportation have the advantages of high hydrogen storage density per unit volume and high transportation efficiency,making it convenient for large-scale and long-distance offshore hydrogen energy transportation.The main low-temperature heat exchanger is the core equipment of the hydrogen liquefaction refrigeration section,and the phase change heat transfer process of the low-temperature working fluid in the hydrogen liquefaction process often occurs inside the main low-temperature heat exchanger.Spiral wound heat exchangers have been widely used in hydrogen liquefaction because of their high heat transfer coefficient,low refrigerant filling amount,and compact structure.The temperature of the hydrogen liquefaction process is relatively low,and self-compensation for the thermal expansion/cold contraction of the spiral wound heat exchangers is more obvious.[Methods]To facilitate the low-temperature transportation of hydrogen energy,a floating porous medium channel is formed by the addition of a normal secondary hydrogen conversion catalyst in the pipeline of a spiral wound heat exchanger.Unlike the environment on land,when applied on floating offshore platforms,the multidegree of freedom shaking sea conditions have a significant impact on the liquid phase flow with free interfaces,which can cause uneven fluid distribution inside and outside porous media channels,affecting the safety and efficiency of the equipment.To enhance teaching activities in offshore new energy(e.g.,hydrogen energ
