摘要
基于简单偶极子模型计算磁流变液体系的自由能,考虑了体系中粒子的渗透压,研究磁流变液的液固相变.结果发现当外加磁场超过一临界值时,体系发生由液相向固相的转变,同时温度变化也引起磁流变液的相变.
The free energy of magnetorheological (MR) fluids is calculated basing on the model of simple dipoles,the osmotic pressure of the system is considered,the phase transition of MR fluids is studied.The results show that Magnetorhiological Fluids expriences a liquid phase to a solid phase when the applied magnetic field exceeds critical magnetic field.In addition,the phase transition can occur with the change of temperature.
