摘要
采用毛细管粘度计测量了Cu-H2O纳米流体的粘度,研究了pH值、分散剂加入量和纳米颗粒质量分数对纳米流体粘度的影响.结果表明在液体中添加纳米颗粒,其粘度发生了变化,但不同因素对纳米流体粘度的影响不同.在最佳pH值和分散剂加入量时,纳米颗粒质量分数对粘度的影响较大.
The viscosity of Cu-H2O nanofluid is measured by using capillary viscometers, and the effects of pH value, SDBS dispersant concentration and particle concentration on the dynamic viscosity of Cu-H2O nanofluid are experimentally investigated. It has been found that under the optimum pH and SDBS dispersant concentration conditions, particle concentration greatly effect affects the dynamic viscosity of Cu-H2O nanofluids.
