本研究将定向分布的多壁碳纳米管（MWCNT）应用于去离子水凝固过程的过冷抑制和热导率的提高。具体地说，包裹在MWCNT上的fe3o4纳米粒子被磁化，并沿着外加磁场的方向定向排列。对水基MWCNT纳米流体的凝固特性进行了对比研究。结果表明，在磁场强度为150 mT时，磁性为0.1%的MWCNT纳米流体的导热系数提高了31%，充分显示了其轴向导热系数，潜热的降低与纯水相比可忽略不计。结果表明，磁性MWCNT纳米流体在磁场作用下具有最佳的凝固特性，过冷度降低68%，总凝固时间提前36%。分析了固液界面的动力学特性，得到了冰晶的生长速度。
In this work, directionally distributed Multi-walled Carbon Nanotube (MWCNT) were applied for supercooling suppression and improving the thermal conductivity of deionized water during the solidification. Specifically, Fe3O4nanoparticles coated MWCNT are magnetized which would be directionally arranged along with the direction of extra magnetic field. A comparative study of solidification characteristics of the water based MWCNT nanofluids was carried out. The results indicated that 0.1% magnetic MWCNT nanofluid shows 31% enhancement in the thermal conductivity under the magnetic field intensity of 150 mT for fully display their axial thermal conductivity, and it exhibits ignorable reduction in the latent heat compared to the pure water. As a result, the magnetic MWCNT nanofluid has the optimal solidification characteristics under the magnetic field with 68% reduction in supercooling and 36% advance in the total solidification time. Moreover, the dynamic characteristics of solid/liquid interface were discussed, and then the growing velocity of ice crystal is obtained.
