單組分氣體、多組分氣體或彼此能溶解的液體都是單相流體，而固體顆粒、液體顆粒懸浮在氣體介質(zhì)中，這樣的流體則為多相流。在除塵技術(shù)中，含塵氣體在管道中的流動過程可以按單相流體處理，而粉塵在除塵器中的分離過程則必需按多相流體處理。流體的壓縮性和膨脹性: 流體受壓力作用時(shí)體積縮小、密度增大的性質(zhì)稱為流體的壓縮性。流體隨著溫度的升高體積膨脹、密度減小的性質(zhì)，稱為流體的膨脹性。在工程上，對于氣流速度遠(yuǎn)小于聲速且處于常溫常壓條件下的氣體，可近似地認(rèn)為是不可壓縮的氣體。如在常溫常壓下工作的除塵器、風(fēng)機(jī)、通風(fēng)管道等裝置中的氣體都可按不可壓縮流體進(jìn)行處理；而對于在高溫高壓下的流動的氣體則必需按可壓縮流體處理，否則將會導(dǎo)致較大誤差。</p><p style="text-indent:25px">19世紀(jì)，工程師們?yōu)榱私鉀Q許多工程問題，尤其是要解決帶有粘性影響的問題。于是他們部分地運(yùn)用流體力學(xué)，部分地采用歸納實(shí)驗(yàn)結(jié)果的半經(jīng)驗(yàn)公式進(jìn)行研究，這就形成了水力學(xué)，至今它仍與流體力學(xué)并行地發(fā)展。1822年，納維建立了粘性流體的基本運(yùn)動方程;1845年，斯托克斯又以更合理的基礎(chǔ)導(dǎo)出了這個(gè)方程，并將其所涉及的宏觀力學(xué)基本概念論證得令人信服。這組方程就是沿用至今的納維-斯托克斯方程(簡稱N-S方程)，它是流體動力學(xué)的理論基礎(chǔ)。上面說到的歐拉方程正是N-S方程在粘度為零時(shí)的特例。通常在數(shù)據(jù)控件上運(yùn)用波紋這種粗細(xì)形式的流體。</p><div

style="text-indent:25px">當(dāng)來流速度接近或超過聲速時(shí)，會產(chǎn)生激波，帶來額外的激波阻力。本質(zhì)上說，激波阻力也是一種壓差阻力，是由于激波的存在，使物體后半部的壓力恢復(fù)不夠而造成的。忽略黏性損失，當(dāng)沒有激波時(shí)，氣流在物體后半部減速對應(yīng)一個(gè)壓升Δp1 ；當(dāng)存在激波時(shí)，氣流經(jīng)過激波時(shí)部分損失了部分機(jī)械能，同樣的減速對應(yīng)的壓升Δp2 就會比Δp1 要小。因此，有激波時(shí)物體后半部的壓力要低一點(diǎn)，這就是激波阻力的來源。把物體前緣做成尖的可以減小激波錐角，從而減小激波帶來的損失，也就減小了激波阻力。船在水面行進(jìn)時(shí)會產(chǎn)生水面波，也會有波阻力，所以要做成尖頭的，而在水下行進(jìn)的潛艇則是圓頭的。流體是液體和氣體的總稱。山東軟管總成流體元件廠</p><p
