摘要
通过添加素水性分散剂，经过超声振动制备了粒径为20hm的4种不同质量分数的TiO2-水纳米复合流体。对去离子水和纳米复合流体同步进行蓄冷和释冷实验，实验表明：加入纳米TiO2粉体后，可大幅度降低水的过冷度直至消除，并且纳米复合流体的起始成核时间比去离子水提前了，融冰时TiO2-水纳米复合流体的释冷率要比去离子水大。
Four different concentration nanofluids with 2Onto TiO2 are prepared by supersonic oscillator with hydrophilic dispersant. Deionizecl water and nanofluids are tested by the experiments of freezing and melting synchronously. The resuits show that nanofluids have remarkable lower super-cooling degree than that of deionizecl water, and the time of beginning nucleation is ahead of deionizecl water. The melting rate of deionizecl water is lower than TiO2 nanofluids.
