| 摘 要： | 建立磁场作用下水平圆管内磁性潜热型功能流体对流换热的数学物理模型,分析磁场强度、磁性相变微胶囊体积分数、流体质量流量等因素对流体对流换热的影响.磁场对磁性潜热型功能流体的对流换热具有显著的强化作用,磁场强度愈大强化作用愈明显,强化原因是磁性相变微胶囊受到磁力作用产生扰动.

| Abstract: | A mathematical model is established to describe convective heat transfer in magnetic microencapsulated phase change material slurry(MMPCMS) flows in a circular tube under an external magnetic field.Influences of magnetic field strength,volume fraction of magnetic phase change materials(MMPCM),mass flow rate,and heat flux on convective heat transfer are analyzed.It shows that convective heat transfer of slurries is obviously enhanced by external magnetic field.Since distributions of MMPCM volume fraction and slurry temperature are changed due to magnetic force on MMPCM. |
