摘要
采用了X-Y函数记录仪，且用45钢做温度探头，研究了水基碳纳米管（CNT）纳米流体的冷却特性。结果表明，在未添加十二烷基苯磺酸钠（SDBS）条件下，800℃以下，随CNT含量的增加，水基CNT纳米流体的冷却性能逐渐下降。在添加SDBS条件下，在770—440℃随CNT含量的增加，水基CNT纳米流体的冷却性能增大。相同CNT含量条件下，加分散剂的水基纳米流体的冷却速度明显低于未加分散剂的纳米流体。
Cooling curves of water based carbon nanotube （CNT） nanofluids was investigated by X-Y recorder and temperature probe with 45 steel. The results show that, below 800 ℃, with CNT content increasing, the cooling capacity of water based CNT nanofluid decreases without SDBS adding. At 770440 ℃, with CNT content increasing, the cooling capacity of water based CNT nanofluid increases with SDBS adding. At the same CNT content, the cooling rate of the water based CNT nanofluid with SDBS is significantly lower than that of the nanofluid without SDBS.
