臨界流文丘利噴嘴的基本原理1.原理臨界流文丘利噴嘴是個(gè)孔徑逐漸減小的流道，孔徑小的部分稱為喉部，在喉部的后面有孔徑逐漸擴(kuò)大的流道。噴嘴可隨著其下游擴(kuò)大管長(zhǎng)度的不同可得到不同的臨界壓力比，大可以達(dá)到.9。當(dāng)氣流通過(guò)喉部時(shí)氣流速度可達(dá)到音速，此時(shí)馬赫數(shù)等于1，流量只與上游壓力有關(guān)（與下游壓力無(wú)關(guān)），流出系數(shù)只與雷諾數(shù)有關(guān)。所以適合于作為氣體流量計(jì)量標(biāo)準(zhǔn)使用。數(shù)學(xué)模型在理想條件下，理論上可以導(dǎo)出噴嘴的質(zhì)量流量q為q=AC式中：A噴嘴喉部的內(nèi)截面積；R氣體常數(shù)；C理想條件下的臨界流函數(shù)。
