Abstract  

The interactional and quantitative influences of four factors, mass fraction of carbon nanotube, mass fraction of dispersant, pH value and ultrasonic vibration time, on the stability of carbon nanotube nanofluid were analyzed. Twelve specific sample nanofluids were prepared and their Zeta potentials were measured. Sample values were determined by uniform design method and the stability was evaluated by Zeta potential. The quadratic polynomial stepwise regressive method was applied to dataprocessing; and a regression model between the nanofluid’s stability and four influence factors was established. Results showed that one factor’s influence on nanofluid’s stability was restrained by others. When ultrasonic vibration time was more than 3.411 hours, the stability of the nanofluid was positively correlated to the mass fraction of carbon nanotube; while ultrasonic vibration time was less than 3.411 hours, it was negatively correlated．

基于均匀设计法的碳纳米管纳米流体稳定性

研究碳纳米管质量分数、分散剂质量分数、pH值和超声振荡时间对碳纳米管纳米流体稳定性的交互影响和定量影响.配置12个碳纳米管纳米流体样品,测定各样品的Zeta电位值.样品的4因素取值通过均匀设计法确定,稳定性用Zeta电位表征.采用二次多项式逐步回归法处理数据,建立碳纳米管纳米流体稳定性与4个因素之间的回归模型.由模型分析可知,该4因素对碳纳米管纳米流体稳定性的影响是相互约束的.当超声振荡时间>3.411 h时,碳纳米管纳米流体的稳定性与碳纳米管质量分数正相关；当超声振荡时间<3.411 h时,碳纳米管纳米流体的稳定性与碳纳米管质量分数负相关.
