| 摘 要： | 测量了TiO2-BaC12-H2O纳米流体的粘度,分析了粒子体积分数、温度对纳米流体粘度影响的变化规律.结果表明,纳米流体的粘度随TiO2粒子体积分数的增加呈加速上升的趋势,随温度呈反比变化;体积分数越高的纳米流体,在较低温度下的粘度增幅比高温时大.流变曲线表明,在所配制的体积分数内,TiO2-BaCl2-H2O纳米流...

| Abstract: | TiO2-BaCl2-H2O nano-fluid viscosity was measured,including the regularity of both volume fraction and temperature influence on it.The results show that nano-fluid viscosity changes in direct proportion to TiO2 volume fraction and in inverse proportion to temperature variation;and at lower temperature,the increasing degree of nano-fluid with higher volume fraction exceeds that at higher temperature.The flow curve demonstrates that within a fixed volume fraction,the TiO2-BaCl2-H2O nano-fluid is a classic Newt... |
