| 摘 要： | 测量了不同体积浓度的TiO2-H2O纳米流体在不同温度下的粘度,结果表明,TiO2-H2O纳米流体的粘度显著大于未添加纳米粒子的纯水的粘度值,并且粘度随体积浓度的增大急剧增大,随温度的升高而急剧减小.流变特性表明,在所配制的体积浓度内,TiO2-H2O纳米流体是一种典型的牛顿型流体.

| Abstract: | The viscosities of TiO2-H2O nanofluids suspending different volume fraction of TiO2 nanoparticles are measured under different temperatures.The results indicate that the viscosities of nanofluids increase apparently compared to the water without dispersed nanoparticles.It is also clear that the viscosities of TiO2-H2O nanofluids increase remarkably with the volume fraction of nanoparticles.And the viscosities vary greatly and oppositely with the temperature of the TiO2-H2O nanofluids.The results demonstrate... |
