摘要

采用"两步法"制备了质量分数分别为0.1%

0.5%

1%的Al2O3-H2O纳米流体

研究了温度在25

0℃范围内纳米流体粘度和相对粘度的变化规律

发现粘度随温度的升高而减小

而相对粘度随温度升高的变化与纳米粒子质量分数有关。质量分数w=0.1%和w=0.5%时

纳米流体相对粘度随温度升高几乎不发生变化

w=1%的纳米流体相对粘度随温度升高变化幅度较大;同时发现温度保持在50℃时

w=0.1%和w=0.5%的纳米流体粘度随恒温保持时间的延长变化很小

而w=1%的纳米流体粘度却减少了14.0%

经恒温保持24 h后自然冷却的纳米流体再次加热

发现其粘度较之前整体有所下降。

Abstract

An experimental investigation employing two-step method is conducted on the viscosities and relative viscosities of Al2O3-H2 O nanofluids with mass fractions of 0. 1 %

0. 5 % and 1 % at range of 25

50 ℃. The results show that viscosities decreased with temperature increasing; however

relative viscosities change with temperature increasing which are related to mass fractions of nanoparticles. Relative viscosities of nanofluids vary barely with temperature rising with fractions of w = 0. 1 % and w = 0. 5 %

whereas amplitude of temperature variation is greater in higher concentration

w = 1 %. Simultaneously

it is demonstr

ated that while temperature is kept at 50 ℃

no significant variation in viscosities of nanofluids with w = 0. 1 % and w = 0. 5 %

while viscosities of nanofluids with w = 1 % decrased by 14. 0 %. Furthermore

an overall decline happened to those viscosities of nanofluids reheated after cooling naturally comparing with the viscosities of nanofluids without keeping constant temperature at 50 ℃ for 24 h.
