style="text-indent:25px">曾有研究人員將高傳熱性能的Cu-水納米流體作為換熱工質(zhì)引入射流技術(shù)，測(cè)試了不同納米粒子體積份額的Cu-水納米流體（平均粒徑25nm）射流沖擊傳熱特性。結(jié)果表明，在水射流介質(zhì)中添加納米粒子，可增強(qiáng)射流系統(tǒng)的散熱冷卻能力。例如，3.0%粒子體積份額的納米流體射流換熱系數(shù)比水提高了52%。Kulkarni等人在50%濃度的乙二醇水溶液里摻加Al2O3納米粒子，作為柴油發(fā)電機(jī)夾套的冷卻工質(zhì)，明顯提高了冷卻效果。Al2O3納米粒子體積濃度6%的納米流體可以將對(duì)應(yīng)于乙二醇水溶液的78.1%換熱效率提高到81.1%。而Tzeng等人分別將CuO和Al2O3納米粒子摻加到冷卻機(jī)油中，以提高四輪驅(qū)動(dòng)汽車動(dòng)力傳遞系統(tǒng)的冷卻效率，避免過(guò)高的熱應(yīng)力產(chǎn)生，終也取得了良好的效果。</p><p style="text-indent:25px">減小阻力是流體力學(xué)永恒的主題。采用流線形可以有效地減小壓差阻力，這主要是因?yàn)樵O(shè)計(jì)良好的流線體表面不存在邊界層分離，從而減小了壓差阻力。分析物體的氣動(dòng)阻力的時(shí)候，流體力學(xué)的習(xí)慣是按照力的作用形式分。垂直作用在物體表面的壓力產(chǎn)生的阻力稱為壓差阻力，而平行于物體表面的摩擦力形成的阻力稱為摩擦阻力。由于物體表面不存在這兩種力之外的力，所以任何一種阻力不是壓差阻力就是摩擦阻力，或者兼而有之。流動(dòng)分離產(chǎn)生的壓差阻力和激波產(chǎn)生的壓差阻力是影響物體氣動(dòng)阻力的大因素。液體的流動(dòng)性不如氣體。</p><div

style="text-indent:25px">理想流體和實(shí)際流體：根據(jù)流體粘性的差別，可將流體分為兩大類，即理想流體和實(shí)際流體。自然界中存在的流體都具有粘性，統(tǒng)稱為粘性流體或?qū)嶋H流體。對(duì)于完全沒(méi)有粘性的流體稱為理想流體。這種流體*是一種假想，實(shí)際并不存在。但是，引進(jìn)理想流體的概念是有實(shí)際意義的。因?yàn)?，粘性的?wèn)題十分復(fù)雜，影響因素很多，這對(duì)研究實(shí)際流體的帶來(lái)很大的困難。因此，常常先把問(wèn)題簡(jiǎn)化為不考慮粘性因素的理想流體，找出規(guī)律后再考慮粘性的影響進(jìn)行修正。這種修正，常常由于理論分析不能完全解決而借助于試驗(yàn)研究的手段。另外，在很多實(shí)際問(wèn)題中粘滯性并不起主要作用。因此，把實(shí)際流體在一定條件下，可當(dāng)作理想流體處理，這樣既抓住了主要矛盾又使問(wèn)題地簡(jiǎn)化。氣體所占的體積是同質(zhì)量液體的103倍，所以氣體的分子距與液體相比要大得多。廣東軟管總成流體廠家</p><p
